what charged particle is produced during ionic bonds
Answer:
An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation or a positively charged ion. The atom gaining one or more electrons becomes an anion which is a negatively charged ion.
Why Do Some Things Stop While Others Keep Going?
Answer:because they run out of energy when it is transferred and to other objects, or their kinetic energy

You have a stock solution of HNO3 with a concentration of 4.5 x 10^-4 M. However, you need 275 ml of a 2.50 x 10^-5 M solution. How much of the stock solution will you need?
Answer:
15.28 mL
Explanation:
From the question given above, the following data were obtained:
Molarity of stock solution (M₁) = 4.5x10¯⁴ M
Volume of diluted solution (V₂) = 275 mL
Molarity of diluted solution (M₂) = 2.5×10¯⁵ M
Volume of stock solution (V₁) needed =.?
The volume of the stock solution needed can be obtained by using the dilution formula as illustrated below:
M₁V₁ = M₂V₂
4.5x10¯⁴ × V₁ = 2.5×10¯⁵ × 275
4.5x10¯⁴ × V₁ = 0.006875
Divide both side by 4.5x10¯⁴
V₁ = 0.006875 / 4.5x10¯⁴
V₁ = 15.28 mL
Therefore, the volume of the stock solution needed is 15.28 mL

What does the formula of an ionic compound tell you?
Answer:
The overall ionic formula for a compound must be electrically neutral, meaning it has no charge. When writing the formula for the ionic compound, the cation comes first, followed by the anion, both with numeric subscripts to indicate the number of atoms of each.

Xylem takes in water, sunlight, and carbon dioxide and releases oxygen.
Stomata take in carbon dioxide and release oxygen.
Answer:
Stomata take in water, sunlight, and carbon dioxide and release oxygen.
Explanation:
Photosynthesis collects and absorbs sunlight and converts the sunlight into sugars (glycose), then the plant stores the sugar and uses it.

Name three sources of atmospheric carbon dioxide. (Write in complete sentences and be very detailed.)
This is science.
First and best answer gets 5 stars, a thanks, and a brainliest!
Doing this because I know I'm kickass at Chemistry.
One source would be human emissions. As humans, we use a lot of machines (like power plants) that produce large amounts of carbon dioxide into the atmosphere. The ocean also produces a lot of carbon dioxide via the evaporation cycle. Polluted waters eventually will go into the atmosphere. Volcanoes, even when not erupted, emit a lot of carbon dioxide as well. Dormant underground magma releases carbon dioxide through the Earth's pores, and even when a volcano erupts, it produces carbon dioxide as well.

What is the percent composition of Phosphorus in Li3PO3
Answer:
you will get 17.983 g of lithium for every 100 g of lithium phosphate.
Explanation:
69.7% is the percent by mass of Lithium in Li[tex]_3[/tex]PO[tex]_3[/tex]. A percent is obtained by multiplying the result by 100.
One approach to show the concentration for an element within a compound or component in a combination is as a mass percentage. The mass percentage is computed by dividing the total weight of the combination by the mass of each component and multiplying the result by 100%. The mass percent is calculated by dividing the mass that contains the compound and solute by the mass for the element or solute.
99.795g/mol = molar mass of Li[tex]_3[/tex]PO[tex]_3[/tex]
6.94g/mol = molar mass of Li
mass percentage of Li=(molar mass of Li/molar mass of Li[tex]_3[/tex]PO[tex]_3[/tex])× 100
=(6.94/99.7)× 100
=69.7%

The compound has the empirical formula of CH. Give some possible molecular formulas for this compound if you didn't know the molar mass.
Answer:
Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is represented by subscripts in the empirical formula.

The density of mercury is 13.6 g/mL. What is the mass of 3,426 mL of mercury?
Answer:
m = 46593.6 g
Explanation:
Given data:
Mass of mercury = ?
Volume of mercury = 3426 mL
Density of mercury = 13.6 g/mL
Solution:
Formula:
d = m/v
d = density
m = mass
v = volume
by putting values,
13.6 g/mL = m/ 3426 mL
m = 13.6 g/mL × 3426 mL
m = 46593.6 g

What is the volume of a balloon that contains a 1.00 mol sample of oxygen with a pressure of 2.00 atm at 300.0 K?
Answer:
12.3
Explanation:
Trust
Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, 12.3L is the volume of a balloon that contains a 1.00 mol sample of oxygen with a pressure of 2.00 atm at 300.0 K.
What is ideal gas equation?Ideal gas equation is the mathematical expression that relates pressure volume and temperature. There is no force of attraction between the particles.
Mathematically the relation between Pressure, volume and temperature can be given as
PV=nRT
where,
P = pressure of oxygen gas= 2.00 atm
V= volume of oxygen gas =?
n =number of moles of oxygen gas=1.00 mol
T =temperature of oxygen gas =300.0 K
R = Gas constant = 0.0821 L.atm/K.mol
Substituting all the given values, we get
2.00×V=1× 0.0821×300.0
On calculation we get
Volume=12.3L
Therefore, the volume of oxygen is 12.3L.

How is the rock in the deep mantle similar to the rock in the parts of the mantle nearest the surface? How is it different?
Answer:
Similarity: Rocks within the mantle contain more magnesium and iron than the ones in the crust.
Difference: Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly. On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.
Explanation:

What is Rocks?
Rocks in the deep mantle are under intense heat and pressure. In this case, they are semi-solid rocks that flow slowly.
On the other hand, the part of the mantle that is nearest to the surface consists of rigid rocks. It has a lower temperature than the rocks in the deep mantle.
According to geologists, a rock is a naturally occurring material made up of crystalline crystals of various minerals that have fused together to form a solid mass.
