Answer:
The mass of the neon gas m = 1.214 kg
Explanation:
Pressure = 3 atm = 304 k pa
Volume = 0.57 L = 0.00057 
Temperature = 75 °c = 348 K
Universal gas constant = 0.0821 
We have to change the unit of this constant. it may be written as
Universal gas constant = 8.314 
Gas constant for neon = 
= 0.41 
From ideal gas equation,
P V = m R T ------- (1)
We have all the variables except m. so we have to solve this equation for mass (m).
⇒ 304 × 
× 0.00057 = m × 0.41 × 348
⇒ 173.28 = 142.68 × m
⇒ m = 1.214 kg
This is the mass of the neon gas.
Churning or mixing food.
The stomach is a muscular sac that lies between theesophagus and thesmall intestine in the upper abdomen. The stomach is not the only part of your digestive system that absorbs food but rather is a part of the digestive system and important for churning food into a consistency that is easier to digest for the rest of your intestines.
First let us see what
kind of bonds are formed in the compound. By drawing the structure, we see that
the kind of bonds are:
N =- triple bond -= C –
O
<span>So there is only
single bond between C and O therefore the hybridization of C is sp.</span>
The sample response given in the question is right.
To find the answer, we need to know more about the distance and displacement.
<h3>How distance differ from displacement?</h3>
- Displacement is the shortest distance between the initial and final points of a body.
- It is the change in position with a fixed direction.
- Displacement is a vector quantity and can be positive, negative or zero values.
- Distance is the length of actual path of the body between initial and final positions.
- It's a scalar quantity and it can be positive or zero.
- The magnitude of displacement is less than or equal to the distance travelled.
Thus, we can conclude that the given sample response is right.

Answer:
3M
Explanation:
Molarity is one of the measures of the molar concentration of a solution, which can be calculated by using the formula below:
Molarity = number of moles ÷ volume
From the information given in this question, 4 liters of a solution contains 12 moles of sugar. This means that n = 12mol and V = 4L
Molarity = n/V
Molarity = 12/4
Molarity = 3
Hence, the molarity of the sugar solution is 3mol/L or 3M
