Answer:
0.454moles
Explanation:
Calculate the molar mass of AgBr
Ag=108
Br=80
Molar mass= 108+80
Molar mass=188g/mol
It's mole to gram question
2moles of Na2S2O3= 188g of AgBr
X moles of Na2S2O3=42.7g of AgBr
Cross multiply
188x=2×42.7
X= 85.4/188
X=0.454moles
Explanation:
1=2 atoms
2=4-n where n is the number of bonds to that carbon
3=10
4=2

Answer:
The pressure in mmHg is 59.
Explanation:
Given data:
Pressure of air inside balloon = 0.78 atm
Pressure in mmHg = ?
Solution:
mmHg:
mmHg is referred as manometric unit of pressure. It is define as the pressure exerted by mercury column at height of one millimeter.
Symbol:
"mmHg"
Atmosphere (atm)
atm is unit of pressure. It is used as a standard unit. It is equal to the 101325 Pa.
1 atm = 760 mmHg
Inorder to convert the atm into mmHg we will multiply the given atm value with 760.
0.78 atm × 760 mmHg / 1 atm = 592.8 mmHg
59 mmHg or 59
Answer:
The energy transferred between samples of matter because of a difference in their temperatures is called a. heat.
Explanation:
The first law of thermodynamics establishes that when two bodies with different temperatures are put in contact they will find thermic equilibrium to a final temperature by transferring heat. Thus the correct answer is (a).
Thermochemistry is the study of the transformations of heat energy on the chemical reactions. Chemical kinetics is the study of the rate of chemical reactions. And temperature is the measure of the heat.
