<u>Answer:</u> The oxidation number of magnesium in magnesium chloride is +2.

<u>Explanation:</u>

Oxidation number is defined as the number that is assigned to an element when it gains or looses electrons. If an element gains electron, it will attain a negative oxidation number and if an element looses electron, it will attain a positive oxidation number.

The chemical formula for magnesium chloride is MgCl_2

We take the oxidation state of magnesium atom be 'x'.

Oxidation state of chlorine atom = -1

Evaluating the oxidation number of magnesium atom:

x+2(-1)=0\\\\x=+2

Hence, the oxidation number of magnesium in the given compound is +2.

A balloon full of air has a volume of 1.00L at a temperature of 23 °C. What is the balloon's volume at 33°C?
igomit [66]

Answer:

V2= 1.03L

Explanation:

Start off with what you are given.

V^1: 1.00L

T^1: 23°C

V^2?

T^2: 33°C

If you know your gas laws, you have to utilise a certain gas law called Charles' Law:

V^1/T^1 = V^2/T^2

Remember to convert Celsius values to Kelvin whenever you are dealing with gas problems. This can be done by adding 273 to whatever value in Celsius you have.

(23+273 = 296)     (33+273 = 306)

Multiply crisscross

1.00/296= V^2/306

296V^2 = 306

Dividing both sides by 296 to isolate V2, we get

306/296 = 1.0337837837837837837837837837838

V2= 1.03L

Newton's second law of motion is F = ma.
ZanzabumX [31]

<u>Answer:</u> The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

<u>Explanation:</u>

Force is defined as the product of object's mass and acceleration.

Mathematically,

F = ma     ......(1)

or,

a = F/m      .....(2)

where,

F = Force exerted on an object = 60N

m = mass of an object = 30kg

a = acceleration of the object = ?

Putting values in above equation, we get:

a = 60 kg.m/s^2/30 kg = 2m/s^2

The acceleration of the car is 2m/s^2.

From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.

And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.

Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.

Find the volume of a gold ring that has a mass of 12.00 grams. The density of gold is 19.30 g/mL. The volume is
kozerog [31]

Answer:

<h3>The answer is 0.622 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass = 12 g

density = 19.30 g/mL

We have

volume =  \frac{12}{19.30}  \\  = 0.62176165...

We have the final answer as

<h3>0.622 mL</h3>

Hope this helps you

How does a conclusion differ from an inference?
Setler79 [48]

Answer:

the difference between the two. Inference: Inference is something that uses facts to determine other facts. ... Inference can be accurate or inaccurate, justified or unjustified, logical or illogical. Conclusion: A conclusion is the next logical step in the information series.

Explanation:

Inferences and conclusions from that analysis can be powerful tools for understanding people and the decisions that they make. An inference is an assumed fact based on available information. A drawn conclusion is an assumption developed as a next logical step for the given information.
