Andrews [41]

Thrust acts on the spacecraft and propels in the space.

<h3>How space shuttles move?</h3>

1. The force created by the shuttle's engines in expelling the burning fuel produces an equal thrust in the opposite direction. This thrust acts on the spacecraft and propels in the space.

2. The thermosphere and the stratosphere are our hottest atmosphere layers because these two layers are present near the sun as compared to other layers of atmosphere.

3. When the meteors hit the atmosphere, meteors rub against air particles and create friction which is heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.

A solution of malonic acid, H2C3H2O4 , was standardized by titration with 0.1000 M NaOH solution. If 21.17 mL of the NaOH soluti
MrRa [10]

Answer: The molarity of the malonic acid solution is 0.08335 M

Explanation:

H_2C_3H_2O_4 +2NaOH\rightarrow Na_2C_3H_2O_4+2H_2O

To calculate the molarity of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is H_2C_3H_2O_4

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is NaOH.

We are given:

n_1=2\\M_1=?\\V_1=12.70mL\\n_2=1\\M_2=0.1000M\\V_2=21.17mL

Putting values in above equation, we get:

2\times M_1\times 12.70=1\times 0.1000\times 21.17\\\\M_1=0.08335M

Thus the molarity of the malonic acid solution is 0.08335 M

This download is my science worksheet. It's about different types of energy in a situation, like examples. btw this is 7th grade
scoray [572]

All types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

<h3>What is kinetic energy?</h3>

Energy is the ability to perform a given work. Kinetic energy is energy in movement, whereas potential energy is stored energy.

For example, plant photosynthesis makes reference to chemical energy (potential energy), popcorn makes reference to thermal energy, etc.

In conclusion, all types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.
