Answer:
C
green traveled les distance but still ended up in the same location as red
Answer:
umm.. B. a base that generates a lot of hydroxide ions in water.
The specific heat of a substance is heat released or absorbed by one gram for a change in 1 degree celsius
so higher the specific heat, more the heat required to raise the temperature by same extent or more the heat released on decrease in temperature upto same extent (for two substance)
Here the specific heat of sandy clay is 1.4 J/g °C
So it is less than that of wet mud hence sandy clay is needs to release less energy to decrease its temperature
Atomic number = protons
Protons = P Electrons = E P = E
Atomic mass = Neutrons + Protons
Atomic number = atomic mass = neutrons
P = E
AM - AN = N
Example:
Calcium = 20 Protons 20P = 20E
Atomic mass - atomic number = neutrons :)
Identify each of the following as a product or a coefficient in reaction below
<h2> 2H^+ + CO3^2- → H2O + CO2</h2><h2 /><h2 /><h3> <u><em>reactant are</em></u></h3><h2> H^+ and CO3^2-</h2>
<u><em>Reason: </em></u>Reactant of a chemical reaction are found in the left side. They are initially present in a chemical reaction which are consumed to form product.
<h3> <em><u>Product are</u></em></h3>
H2O and CO2
<u><em>Reason</em></u>: They are found in the right side of the reaction. Product are produced in a chemical reaction.
<em><u>coefficient</u></em>
<em><u> </u></em><em><u> </u></em>is 2
- Coefficient is the number found in front of a formula.
- Therefore 2 is the coefficient since it is found in front of H^+
