Answer:
D) The amount of heat a substance can hold.
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
The substances with higher value of specific heat capacity require more heat to raise the temperature by one degree as compared the substances having low value of specific heat capacity.
For example,
The specific heat capacity of oil is 1.57 j/g. K and for water is 4.18 j/g.K. So, water take a time to increase its temperature by one degree by absorbing more heat while oil will heat up faster by absorbing less amount of heat.
Hey there!
Molar mass ( NH4)2SO4 = 132.1395 g/mol
So:
1 mole ( NH4)2SO4 ---------------- 132.1395 g
moles (NH4)2SO4 ----------------- 3.30 g
moles (NH4)2SO4 = 3.30 * 1 / 132.1395
moles (NH4)2SO4 = 3.30 / 132.1395
=> 0.0250 moles of (NH4)2SO4
Answer A
Hope that helps!
Nuetrons+protons. and number 7 is electrons and protons
Answer:
Try using Ptable or chemicalaid
Explanation:
Ptable is a great website that shows you a dynamic periodic table. It can show you which elements are Halogens, Alkali metals, transition metals, noble gases, and etc!
Chemicalaid is a nice website to find out more information about specific elements, it also lists every element on the periodic table.
Answer:
3189.07Pa
Explanation:
The conversion of 23.92mmH to Pa can be achieved in the following way:
760mmHg = 101325Pa
23.92mmHg = (23.92x101325)/760 = 3189.07Pa
