False, a physical change means that the property of matter will change size, shape, color, or density. These are all examples of physical change.
Answer:
1.788 C DEGREES
Explanation:
STP is 1 atm at 273.15 K
P1V1/T1 = P2V2/T2
(1)(62.65) / (273.15) = (612/760)(78.31)/T2
T2 = 274.93 K = 1.788 C
Sorry, I don’t believe in Jesus or god etc but thnx???
Answer:
<h2>The answer is 63.24 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 62 mL
density = 1.02 g/mL
The mass of the water is
mass = 1.02 × 62
We have the final answer as
<h3>63.24 g</h3>
Hope this helps you
Answer:
Single replacement reaction
Explanation:
It's already balanced so it would just be Mg + H2SO4 --> H2 + MgSO4
The formula for a single replacement reaction is
A + BC --> B + AC
A=Mg
B=H2
C=SO4
