Answer:

7.3*10^2 K = 457 C = 854.33 F

Explanation:

<u>Given:</u>

Surface temperature on sun = 7.3*10^2 K

<u>To determine:</u>

The temperature in degrees C and Kelvin

<u>Calculation:</u>

To convert Kelvin(K) to degrees Celsius (°C)

C = K -273----(1)

To convert Kelvin(K) to degrees Fahrenheit (F)

F = K*\frac{9}{5}-459.67----(2)

Based on equation (1):

C = 730 -273 = 457 C

Based on equation (2)

F = 730*\frac{9}{5}-459.67=854.33 F

The force of 20 N acts upon a 5kg block. What is the acceleration of the block?
charle [14.2K]

Answer:

<h2>The answer is 4 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

where

a is the acceleration

f is the force

m is the mass

From the question

f = 20 N

m = 5 kg

We have

a =  \frac{20}{5}  \\

We have the final answer as

<h3>4 m/s²</h3>

Hope this helps you

A stock solution has a concentration of 1.5 M NaCl and is diluted to a 0.80 M solution with a volume of 0.10 L. What volume of t
ioda

Answer:

0.053 L  is the volume of concentrated solution that was used

Explanation:

Let's determine the answer of this, by rules of three.

There is also a dilution formula.

Molarity is a sort of concentration that indicates the moles of solute in 1L of solution.

In 1 L of concentrated solution, there are 1.5 moles of NaCl

In 1 L of diluted solution, there are 0.80 moles.

The volume for the diluted solution is 0.10L

The rule of three will be:

1L of solution has 0.80 moles of solute

Then, 0.10L of solution must have (0.1 . 0.8)/1 = 0.08 moles

This moles came from the concentrated solution, and we know that in 1L of this solution we have 1.5 moles. Therefore the rule of three will be:

1.5 moles are in 1L of solution

0.08 moles were in (0.08 . 1L / 1.5) = 0.053 L (This is the volume of concentrated solution that was used)

Dilution formula is: M conc . Vol conc = M diluted . Vol diluted

1.5 M . Vol conc = 0.80 M . 0.10L

Vol conc = 0.80 M . 0.10L / 1.5M = 0.053L

4NH3 + 3O2 --&gt; 2N2 + 6H2O
larisa86 [58]

The balanced reaction is:

4NH3 + 3O2 --> 2N2 + 6H2O

 <span>We are given the amount of reactants to be used for the reaction. This will be the starting point of our calculation.</span>

83.7g of O2 ( 1 mol / 32 g) = 2.62 mol O2

2.81 moles of NH3

From the balanced reaction, we have a 4:3 ratio of the reactants. The limiting reactant would be oxygen. We will use the amount for oxygen for further calculations.

<span>2.62 mol O2</span><span> (6 mol H2O  / 3 mol O2) (18.02 g H2O / 1 mol H2O) = 94.42 g H2O</span>
