Ca=40
C=12
O=16
1 mole of CaCO3 has 100 grams
So 50 grams is 0.5 mole
Cloning<span> occurs when identical twins, triplets, and so on are born or when a cutting from a plant is used to generate another plant. It also occurs in organisms that reproduce by asexual reproduction, such as bacteria and yeast.</span>
Answer:
FALSE
Explanation:
Assuming that the gas is ideal
Therefore the gas obeys the ideal gas equation
<h3>Ideal gas equation is </h3><h3>P × V = n × R × T</h3>
where
P is the pressure exerted by the gas
V is the volume occupied by the gas
n is the number of moles of the gas
R is the ideal gas constant
T is the temperature of the gas
Here volume of the gas will be the volume of the container
Given the volume of the container and number of moles of the gas are constant
As R will also be constant, the pressure of the gas will be directly proportional to the temperature of the gas
P ∝ T
∴ Pressure will be directly proportional to the temperature
Explanation:
The scale is pushing back up against her feet with the same amount of force but in negative direction.
This can be explain using Newton's third law of motion which states that "action and reaction are equal and opposite".
As the girl weight pulls down on the scale in a positive way with a force of 42N, the scale pulls back with an equal amount of force upward in another direction.
The net force here is zero this is why the scale is not damaged by her weight.
