The pressure that will be exerted if four sample of gas are placed in a single 3.5 container is calculated as below
if each gas occupies 675 mmhg
what about 4 gases in the sample
by cross multiplication
= 675 mm hg x 4/1 = 2.7 x10^3mmhg (answer D)
The coefficients that will balance the tarnishing reaction equation are: 2, 1, 1,1
What is a chemical equation
Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
Thus, we can obtain the coefficients that will balance the tarnishing reaction equation by simply balancing the equation:
How to balance the equation
Ag(s) + H₂S(g) → Ag₂S(s) + H₂(g)
There are 2 atoms of Ag on the right side and 1 atom on the left side. It can be balanced by writing 2 before Ag as shown below:
2Ag(s) + H₂S(g) → Ag₂S(s) + H₂(g)
Thus, the equation is balanced.
The coefficients are: 2, 1, 1, 1 :)
Answer:
<em><u>Energy is released.</u></em> In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy.
Weight is properly defined as how much gravity acts upon an object.
I hope this helps!
The radius of the aluminum cylinder is 0.258cm
HOW TO CALCULATE VOLUME OF A CYLINDER:
- The volume of a cylinder can be calculated by using the formula below:
V=πr²h
Where;
V = volume (cm³)
r = radius (cm)
h = height (cm)
- To calculate the radius of the aluminum cylinder, the volume is required. The volume can be calculated using the formula as follows:
Volume = mass ÷ density
Volume = 1.22 ÷ 2.70
Volume = 0.452 cm³
- The radius can be calculated with the volume and height known as follows:
r = √v/πh
r = √0.452 ÷ (3.142 × 2.16)
r = √0.452 ÷ 6.78
r = √0.067
r = 0.258cm
Therefore, the radius of the aluminum cylinder is 0.258cm.
