Which of the following is a correct description of energy transfer within an endothermic reaction?
Answers
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.

You have 9.3 mL of a 0.031 M solution of NaOH. If you add this solution to 8.5 mL of a 0.012 M solution of crystal violet, what is the initial concentration of NaOH in the reaction mixture?
Answers
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

Carbon dioxide
Sugar
Nitrogen
Answers
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.

One mole of zinc has a mass of 65.4 grams. Approximately how many atoms of zinc are present in one mole of zinc?
Answers
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)

[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

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
Set up conversion: [tex]\displaystyle 255 \ g \ Mg(OH)_2(\frac{1 \ mol \ Mg(OH)_2}{58.33 \ g \ Mg(OH)_2})(\frac{1 \ mol \ MgCl_2}{1 \ mol \ Mg(OH)_2})(\frac{95.21 \ g \ MgCl_2}{1 \ mol \ MgCl_2})[/tex]Multiply/Divide: [tex]\displaystyle 416.227 \ g \ MgCl_2[/tex]Step 4: Check

A. Phosphorus (P)
B.Helium (He)
C. Beryllium (Be)
D. Sulfur (S)
Answers
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.
What is Ions?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.
