B. Interrogative questions/sentences often have to get a yes/no answer.

C. The "next year" will be the answer to that question. U need to ask when.

D. The have not done the work yet, therefore the answer would change from "not finish" to "have not finished"

E. Indirect speech is speech which tells you what someone said. It's like the game "telephone" indirect speech is what you tell someone else, what another person said, or what someone else tells you what another person said.

F. Passive voice means that a subject is a recipient of a verb's action.

The compounds that can dissociate in water from the options given below are;

Ba(NO3)2

CaSO4

Mg3(PO4)2

Dissociation of compound is the process by which compounds degraded into smaller unit which can also recombine to form larger one in another condition.

When ionic compounds dissociate in water, the water molecules separate the ionic crystal. This is because of the attraction between the positive and negative ions in the crystal.

Therefore, The following compounds dissociate in water.

Ba(NO3)2

CaSO4

Mg3(PO4)2

its axis

Explanation:

the earth rotates on its axis 24 hrs a day in relation to the sun.

The amount of energy required to eat 5.25 g of Titanium from 85.5 celsius to 132.5 celsius is 129 joules.

Absorbed or released amount of heat will be calculated by using the below formula as:

Q = mcΔT, where

m = mass of titanium = 5.25g

c = specific heat of titanium = 0.523 J/gram degree celsius

ΔT = change in temperature = 132.5 - 85.5 = 47 degree celsius

On putting these values on the above equation we get,

Q = (5.25)(0.523)(47) = 129 joules

Hence required heat is 129 joules.

Answer:

Explanation: “Insoluble” generally means that a substance does not dissolve in water. Some examples include: sand, fats, wood, metals, and plastic. When we put them in water and try to mix them, they will not dissolve.

Explanation:

Answer:

B.

Explanation:

Energy + SO2(g) -----> S(g) + O2(g) is an edothermic reaction owing to te fact that energy is a reactant in the equation.

An endothermic reaction is one in  wioch energy is supplied to the system in order to enable the breakdown of bonds. Hence, the reaction vessel feels cool as energy is withdrawn from the surroundings.

The reaction;  Energy + SO2(g) -----> S(g) + O2(g) is an edothermic reaction since energy is a reactant in the equation.

Answer:

Molarity=number of moles÷volume(L)

Answer:

Electricity can be present in a static charge, while magnetism's presence is only felt when there are moving charges as a result of electricity. In simple words, electricity can exist without magnetism, but magnetism cannot exist without electricity.

In the Lewis symbol for a fluorine atom, there are 4 paired and 1 unpaired electrons.

However, paired electrons simply means are 2 electrons occupying the same orbital in an atom or molecule of a substance

On the other end, unpaired electron is a single electron that occupies an orbital of an atom.

An atom is the smallest part of an element which can take part in a chemical reaction.

Some atoms of elements are:

In conclusion, in the Lewis symbol for a fluorine atom, there are 4 paired and 1 unpaired electrons.

Explanation:

A. water per day: 20 m/ height: 24cm/ mass: 3.1g B. Water per day: 60 ml/ height: 24cm/ mass: 9.6g

I think that the answer to this question is the third option. These two plants are of the same height but plant B has more mass. So therefore the statement is not true.

If this is a multiple-choice, then I would also select the fourth option along with the third. Plant B received more water, but it is the same height as plant A.

[tex]\rightarrow[/tex]Ozone is an allotropic molecular form of oxygen containing three atoms of oxygen (O3). Ozone O3 is generated through the passage of oxygen O2 through a high voltage potential resulting in the attachment and formation of a third oxygen atom.

[tex]\rightarrow[/tex]The molecular formula for ozone (O3) was established by Soret (1863) by taking the ratio of the change in volumes when O3/O2 mixtures were either heated or exposed to turpentine and cinnamon oil.

[tex]\rightarrow[/tex]Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.
