Answer: Mass is more than 145 g but less than 160 g
Explanation: Acid and limestone reacts forming water, salt and
Carbon dioxide CO2. Because CO2 is gas it is bubbled away from
glass and that's why mass is less than 160 g. Because limestone
releases CO2 and products from acid remain in solution, mass is more than 145 g. If amount of acid in moles is enough, all limestone reacts.
Roughly 44% of mass of limestone CaCO3 forms CO2 and we can estimate mass of gas is 0.44·15 g = 6,6g , so mass would be 153 g

Explanation:
The answer should be RNA but i think DNA would work too
Answer:
Unbalanced force
Explanation:
According to Newton's second law of motion, any unbalanced force that is applied on a body will cause it to have some acceleration.
However, If the force is balanced like the net effect of one force is cancelled by the other, it will result in total force as zero, that will cause zero acceleration in the body.
Newton's second law of motion states:
F=ma
where m is mass and a is acceleration, so it means that is any of these factors is zero , the force will be zero, and hence force is zero only when it is cancelled by some force acting in opposite direction.
For example: When person is dragging the table with a force of 30 N on left side, while the other person is dragging the same table with same force on right side. The table will have zero acceleration.
Hope it help!
