because of gravity hahah

Answer:

Acid rain.

Explanation:

Answer:Endothermic reactions draw heat into the reaction. Heat is transferred from the surroundings into the reaction. The reaction heats up while the surroundings cool down.

Explanation: ice melting in a glass of water would be an example of an endothermic reaction. The ice pulls heat from the water, cooling the water down, but causing the ice to heat up making the ice melt.

Stoichiometry

Step 1: Define

[RxN - Balanced]   MgCl₂ + 2LiOH → Mg(OH)₂ + 2LiCl

[Given]   255 g Mg(OH)₂

[Solve]   x g MgCl₂

Step 2: Identify Conversions

[RxN] 1 mol MgCl₂ → 1 mol Mg(OH)₂

[PT] Molar Mass of Mg - 24.31 g/mol

[PT] Molar Mass of O - 16.00 g/mol

[PT] Molar Mass of H - 1.01 g/mol

[PT] Molar Mass of Cl - 35.45 g/mol

Molar Mass of Mg(OH)₂- 24.31 + 2(16.00) + 2(1.01) = 58.33 g/mol

Molar Mass of MgCl₂ - 24.31 + 2(35.45) = 95.21 g/mol

Step 3: Stoichiometry

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

Answer:

6.02 x 10²³ atoms

Explanation:

The number of moles present in 1 mole of zinc will be 6.02 x 10²³ atoms. This is because a mole of any substance contains the Avogadro's number of particles which is 6.02 x 10²³ atoms.

A mole is simple a convenient way of estimating the number particles within a substance.

So every 1 mole of  a substance contains the same number atom in there.

For the give zinc, since it is 1 mole, it will contain 6.02 x 10²³ atoms

they've changed the answer, but 6.02 x 1023 is still right. the new answer is just 6 x 1023.(6.02 rounded to the nearest integer)

Answer:

Long range

Explanation:

A. But not too sure

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 correct option is option D.

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 ion  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. Sulfur (S) exist as S⁻² as ion which is similar to O²⁻.

Therefore, the correct option is option D.

Answer:

Sugar

Explanation:

The carbon is in form of sugar prior to the lion eating the giraffe. This form of carbon in the giraffe serves as a rich source of nutrient for the lion.

The carbon enters living organisms as carbon dioxide. As it enters, it is converted by plants into glucose, a from of sugar.

When giraffes eats the glucose in plant, it is stored in them and used for the liberation of energy

This same stored chemical energy in the giraffe is taken up by the lion.

Explanation:

Balanced equation

Mg₃(PO₄)₂ + 2Al(NO₃)₃ → 3Mg(NO₃)₂ + 2AlPO₄

Given

Reaction

Mg3(PO4)2 + Al(NO3)3 → Mg(NO3)2 + AlPO4

Required

Balanced equation

Solution

Give a coefficient :

Mg₃(PO₄)₂ + aAl(NO₃)₃ → bMg(NO₃)₂ + cAlPO₄

Make an equation :

Mg, left = 3, right=b⇒b=3

P, left=2, right=c⇒c=2

Al, left=a, right=c⇒a=c⇒a=2

The reaction becomes :

Mg₃(PO₄)₂ + 2Al(NO₃)₃ → 3Mg(NO₃)₂ + 2AlPO₄

Answer:

0.016M is the initial concentration of NaOH in the reaction mixture

Explanation:

The NaOH is diluted from 9.3mL to 9.3mL + 8.5mL = 17.8mL. That is a dilution of:

17.8mL / 9.3mL = 1.914 times

As the initial concentration of the NaOH solution is 0.031M and is diluted 1.914 times, the final concentration of the NaOH solution is:

0.031M / 1.914 =

0.016M is the initial concentration of NaOH in the reaction mixture
