Answer:
One is hands on and one is watching
Explanation:
I just know my science
Answer:
7700000000
Explanation:
so 7.7 x 10 to the power of 9 is in standard form
to put it into a number you just need to times it by 1000000000
however your answer will only have 8 zeros because of the decimal point
The answers that fit the blanks are SMALL and LITTLE, respectively. The particles or molecules or fas are small which makes it loose and easily moves around, and these only exert little attraction for other gas particles. The answer for this would be option D.
Mr: 207.2
m=n×Mr= 6.53×207.2= 1353.02g
Answer:
A. Increasing the temperature will favor forward reaction and more CaCo3 formed.
B. More CaCo3 will be formed.
C. CaCo3 will decrease and more react ants formed.
D. Less CaCo3 will be formed.
E. Iridium is a catalyst so there is no effect
Explanation:
A. Temperature will increase because it's an endothermic reaction.
B. Adding Cao will favor forward reaction and more CaCo3 formed.
C. Removing methane, more react ants are formed and CaCo3 decreases.
D. Irridi is a catalyst so it has no effect on the CaCo3 but only speeds its rate of reaction.
