Answer: Compounds having the same empirical formula are:
Explanation:
Empirical formula tells us about the proportion of the elements present in the compound but it do not tells us about the actual numbers of atoms of the elements present in the compound.
In given empirical formula that is proportion of C:H:O = 1:2:1
In the proportion of C:H:O =2:4:2= 1:2:1
In the proportion of C:H:O =3:6:3= 1:2:1
In the proportion of C:H:O =1:2:2= 1:2:2
In the proportion of C:H:O =5:10:5= 1:2:1
In the proportion of C:H:O =6:12:6= 1:2:1
Compounds having the given empirical formula are:
<h3>
Answer:</h3>
- She needs to know how long it took for her mom to get to her destination.
- She needs to know how far her mom drove.
<h3>
Explanation:</h3>
- Velocity is a vector quantity, which means it has both magnitude and direction.
- It is the ratio of displacement to time taken.
That is; Velocity = Displacement ÷ Time taken
In our case;
Malika needs to determine the velocity of her mom's car.
- Apart from knowing the direction the car travels, she also needs to know the time it takes her mom to reach her destination and how far her mom drove.
- Therefore, if it took her mom time, t seconds to drove for a distance, d meters. Then her mom's car velocity would be;
Velocity, v = d/t m/s
Answer:
It would be A. Air molecules touch the warm ground, Heating them up because conduction is when a source of energy touches something directly.
1 kg = 1000g
15kg = 15000g
