Name the following compound: KI

Suppose we consume a meal and get 850,000 J. How many Calories are ingested?

ollegr [7]

I am Not Sure About Your Question But,

Although every person's daily caloric intake is individual, based on their personal goals and needs, nutrition experts estimate that average daily consumption at each meal should be broken down as follows: 300 to 400 calories for breakfast, and 500 to 700 calories each for lunch and dinner.

A sample of an unknown liquid has a volume of 30.0 mL and a mass of 6 g. What is its density? i need this hella quick

Lana71 [14]

density= mass/volume

density= 6g/30.0 ml

density= 0,2 g/ml

Given: N2 + 3Cl2 → 2NCl3, ΔH = 464 kJ/mol Use the given bond energies and the periodic table to calculate the energy change in t

guapka [62]

The given chemical reaction is:

$N_{2}+3Cl_{2}-->2NCl_{3}$

Δ $H^{0}_{reaction}=$ ∑BE(reactants)-∑BE(products)

= {(941 kJ/mol) + (3 * 242 kJ/mol)} -[{2*(3*200 kJ/mol)}]

= 467 kJ/mol

Calculating the change in heat when 85.3 g chlorine reacts in the above reaction:

Moles of chlorine = $85.3 g Cl_{2}* \frac{1 mol Cl_{2}} {70.91 g Cl_{2} }$

= 1.20 mol $Cl_{2}$

Heat change when 1.20 mol chlorine reacts

= $1.20 mol * \frac{467kJ}{mol} =560.4 kJ$

At the sea shore there is less water so the sun shines directly in them, deeper. there is more water. so their bodies are more in the water therefore the sun is less in their bodies.

Number 14 please help.. chemistry

Zolol [24]

Taking into account the definition of density, the mass of a substance with a volume of 150 cm³ and a density of 1.5 $\frac{g}{cm^{3} }$ is 225 grams.

<h3>What is density</h3>

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

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

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Mass of the substance in this case</h3>

In this case, you know that:
