Answer:
Explanation:
Given that,
A car accelerates negatively from 35m/s to 8m/s in 8s.
We need to find the car's acceleration.
Initial speed, u = 35 m/s
Final speed, v = 8 m/s
Time, t = 8 s
The acceleration of an object is equal to the rate of change of velocity. So,
Put all the values,
So, the acceleration of the car is equal to .
Answer:
<h3>The answer is 0.228 M</h3>
Explanation:
To find the concentration of new solution we use the formula
where
C1 is the concentration of the stock solution
V1 is the volume is the volume of the stock solution
C_2 is the concentration of the diluted solution
V2 is the volume of the diluted solution
Since we are finding the the concentration of new solution
From the question
C1 = 0.575 M
V1 = 298 mL
V2 = 750 mL
We have
We have the final answer as
<h3>0.228 M</h3>
Hope this helps you
Answer: The mole ratio of to is 1: 1
Explanation:
According to the balanced chemical equation ,the number of atoms of each element has to be same on reactant and product side. The stoichiometric coefficients of the species represent their number of moles.
Thus in the reactants, there is 1 mole of and 1 mole of molecule. And thus there is 1 mole of in the product as well.
Thus the mole ratio of to is 1: 1
Answer:
Phosphorus has a low melting point because the intramolecular forces holding it together is London Dispersion Forces.
Explanation:
London Dispersion Forces (LDF) are the weakest intramolecular forces. You don't need to break the covalent bonds, but rather the Van Der Waals' Forces. If LDF are the weakest forces, then the melting point is low.
