In the following reaction, how many grams of H2O are produced if 2.00 g of N2H4 react? N2H4 + 3 O2 ---> 2NO2 + 2H2O

Answers

Answer:

2

Explanation:

From this equation, 2 grams are produced.

The mass of H₂O produced from the reaction is 2.25 g

We'll begin by calculating the mass of N₂H₄ that reacted and the mass of H₂O produced from the balanced equation.

N₂H₄ + 3O₂ —> 2NO₂ + 2H₂O

Molar mass of N₂H₄ = (2×14) +(4×1) = 32 g/mol

Mass of N₂H₄ from the balanced equation = 1 × 32 = 32 g

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass of H₂O from the balanced equation = 2 × 18 = 36 g

SUMMARY

From the balanced equation above,

32 g of N₂H₄ reacted to produce 36 g of H₂O.

Finally, we shall determine the mass of H₂O produced by the reaction of 2 g of N₂H₄

From the balanced equation above,

, 32 g of N₂H₄ reacted to produce 36 g of H₂O.

Therefore,

2 g of N₂H₄ will react to produce = (2 × 36) / 32 = 2.25 g of H₂O

Thus, the mass of H₂O produced from the reaction is 2.25 g

Janet is sliding a box across the floor what does she need to know to calculate the force on a box?

Answer:

Janet needs to know the mass of the box and acceleration .

What is force?

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object  which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton  and is represented by'F'.Newton's second law states that force which acts on an object  is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Unsaturated solution​

Answers

Answer:

See explanation

Explanation:

A saturated solution is a solution that contains just as much solute as it can normally hold at a given temperature in the presence of undissolved solute. An unsaturated solution contains less solute than it can normally hold at a given temperature. A saturated solution can not dissolve more solute whereas an unsaturated solution can comfortably dissolve more solute until it attains saturation at a specified temperature.

There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane​

Answers

Answer:

C. the carbons in ethene are linked by double bonds

Explanation:

The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.

In single bonds afforded with the ethane compound, there is free rotation.

The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.
