Which position of Earth would give a
snowman the best chances of survival
if he is built in the northern
hemisphere?
A. Position A
B. Position B
C. Position C
D. Position D

Answer:

Due to their densities.

Explanation:

Answer:

Liquid water is held together by hydrogen bonds. (Liquid water has fewer hydrogen bonds than ice.) Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water's hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.

Answer:

The coefficient of Ag is 2.

Explanation:

___Ag (s) + ___H₂S (g) ⇒ ___ Ag₂S (s) + ___ H₂(g)

The Law of Conservation of Matter is also called the law of conservation of mass or the Law of Lomonósov-Lavoisier. This law postulates that "the mass is not created or destroyed, only transformed." This means that the reagents interact with each other and form new products with physical and chemical properties different from those of the reagents because the atoms of the substances are ordered differently. But the amount of matter or mass before and after a transformation (chemical reaction) is always the same, that is, the quantities of the masses involved in a given reaction must be constant at all times, not changing in their proportions when the reaction ends.

In others words, the law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts :

Left side: 1 Ag, 2 H and 1 S

Right side: 2 Ag, 2 H and 1 S

The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.  

You can see that the elements H and S are balanced because we have the same quantity on both sides of the reaction. Then you must balance the Ag, so the reaction is:

2 Ag (s) + 1 H₂S (g) ⇒ 1 Ag₂S (s) + 1 H₂(g)

Now you have:

Left side: 2 Ag, 2 H and 1 S

Right side: 2 Ag, 2 H and 1 S

So, you have the same amount of each element to both of the reaction and this is balanced.

Then, the coefficient of Ag is 2.

Explanation:

Answer:

He would travel 3 kilometers.

Explanation:

Since he had already covered 1.5 kilometers in the time of 1 hour that means if he jogged for 1 more hour assuming he is going at the same pace he would've jogged 1.5 kilometers again and when you add that to the 1.5 kilometers he started with it would add up to 3 kilometers.

Answer:

B. The reactants form additional unexpected products.

Explanation:

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

[tex]P_2 = \frac{80000 \times 250}{0.75} = \frac{20000000}{0.75} \\ = 26666666.6666 \\ = 26666667[/tex]

We have the final answer as

Answer:

it is c

Explanation:

Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ions or polyatomic atoms. Therefore the Charlotte's control group in this experiment is  not rubbing the cloth against the PVC pipe or the paper. The correct option is option C.

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state. The Charlotte's control group in this experiment is  not rubbing the cloth against the PVC pipe or the paper.

Therefore the Charlotte's control group in this experiment is  not rubbing the cloth against the PVC pipe or the paper. The correct option is option C.

Answer:

Matter cannot be created destroyed

Explanation

Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

Solar radiation is the primary component that affect weather. Most important factor that influences the weather is the sun's gravitational pull. so option G is correct.

Long-term patterns in climate and weather, as well as their possible effects on human populations, are studied in meteorology. Modern meteorological research places a high priority on the effects of climate change.

The four primary components that affect weather are solar radiation, the quantity of which varies depending on the latitude, orbital distance from the sun, and tilt of the Earth, as well as temperature, air pressure, and the presence of water.

The lower layers of the atmosphere, particularly the troposphere, where most weather occurs, are the focus of meteorology. Meteorologists watch, analyze, and predict our weather using scientific principles. They frequently concentrate on practical weather forecasting .

Thus, Option G is correct.

When a substance melts, the solid gains heat, and the motion of the particles increases (particles move faster in liquid form than in solid form).

Answer:

B substance 2

Explanation:

1. Two substances, both solids, start at the same temperature. You transfer

the same amount of energy into both solids, but substance 1 becomes a

liquid before substance 2. Which substance has a stronger molecular

attraction?

A Substance 1

B Substance 2

Please help I will give you Brainlyest

Substance 2 has a stronger molecular attraction.

Solid is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.

Both solids are supplied with an equal amount of energy. Out of both substances, substance 2 has a stronger molecular attraction due to which it can not easily change into a liquid while substance 1 has a lesser molecular attraction so supplying of few amounts of heat will change substance 1 into a liquid state.

Hence, Substance 2 has a stronger molecular attraction.

Uranium-232 will remain 11.72 g

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually radioactive elements have an unstable atomic nucleus.  

The main particles are emitted by radioactive elements so that they generally decay are alpha (α), beta (β) and gamma (γ) particles  

General formulas used in decay:  

[tex]\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}[/tex]

T = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time

t 1/2 = half-life  = 68.8 years

T = duration of decay  = 344 years

No= initial sample = 375 g

Uranium-232 remain :
