Answer:

yes

Explanation:

math is used constantly to improve one's performance. Achieving the objective of shooting a basketball includes using percentages and angles. By finding the most consistent percentage of shots made while using a certain angle, you can find out which player will score the most baskets.

A 15.0 mL solution of Sr(OH)2 is neutralized with 38.5 mL of 0.350 M

Darya [45]

Answer:

Molarity of Sr(OH)₂ = 0.47 M

Explanation:

Given data:

Volume of Sr(OH)₂ = 15.0 mL

Volume of HCl = 38.5 mL (0.0385 L)

Molarity of HCl = 0.350 M

Concentration/Molarity of Sr(OH)₂ = ?

Solution:

Chemical equation:

Sr(OH)₂ + 2HCl → SrCl₂ +2H₂O

Number of moles of HCl:

Molarity = number of moles/ volume in L

0.350 M = number of moles/0.0385 L

Number of moles = 0.350 mol/L× 0.0385 L

Number of moles = 0.0135 mol

Now we will compare the moles of HCl with Sr(OH)₂.

HCl : Sr(OH)₂

2 : 1

0.0135 : 1/2×0.0135 = 0.007 mol

Molarity/concentration of Sr(OH)₂:

Molarity = number of moles / volume in L

Molarity = 0.007 mol /0.015 L

Molarity = 0.47 M

What particles would you find in a nucleus of an atom

sammy [17]

Answer:

The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.

[25 pts] When a 14.2g sample of a compound containing only mercury and oxygen is decomposed, 13.2g of Hg is obtained. What is th

Agata [3.3K]

Answer:

% composition of Hg = 93 %

% composition of O = 7 %

Explanation:

Data Given:

mass of total sample = 14.2 g

mass of mercury (Hg) = 13.2 g

percent composition of Hg =

percent composition of O =

Solution:

First find mass of oxygen

As this compound only have two components that is oxygen and mercury

upon decomposition it gives 13.2 g mercury

now to find mass of oxygen we have to subtract mass of mercury from total mass of sample

Mass of oxygen = Total mass of sample - mass of Mercury

Mass of oxygen = 14.2 g - 13.2 g

Mass of oxygen = 1 g

Now to find percent composition of Hg and Oxygen

% composition = component mass / total mass of sample x 100. . . .(1)

For % composition of mercury Hg

Put values in equation 1

% composition of Hg = 13.2 g / 14.2 g x 100

% composition of Hg = 93%

For % composition Oxygen (O)

Put values in equation 1

% composition of O = 1 g / 14.2 g x 100

% composition of O = 7 %
