The formula for the compound ammonium chloride?

According to the following position vs. Time graph the bicyclist was

julia-pushkina [17]

Answer:

According to the following position vs. Time graph the bicyclist was : D

D. Not moving for the first two seconds, then begin moving at the constant speed.

Explanation:

$Speed = \frac{Distance}{time}$

Along Y-axis = Distance in meters

Along X-axis = Time taken in second

For first 2 seconds the The object has not changed its position.There is Zero distance covered.So , Speed = 0
After 2 second,The Object changed the distance by equal amount in equal interval of time.(Uniform Speed).Hence at each point after 2 second, there is same value speed

If 1. 3618 moles of AsF3 are allowed to react with 1. 0000 mole of C2Cl6, what would be the theoretical yield of AsCl3, in moles

VARVARA [1.3K]

Answer:

AsF3:C2CI6

4:3

1.3618 moles: 1.02135 moles(1.3618÷4×3)

C2CI6 is the limting reagent

So the number of moles for AsCI3 is 0.817 moles( number of moles of the limting reagant) ÷3 ×4 (according to ratio by balancing chemical equation)=1.09 moles(3 s.f.)

or

Balanced equation

4AsF3 + 3C2Cl6 → 4AsCl3 + 3C2Cl2F4

Use stoichiometry to calculate the moles of AsCl3 that can be produced by each reactant.

Multiply the moles of each reactant by the mole ratio between it and AsCl3 in the balanced equation, so that the moles of the reactant cancel, leaving moles of AsCl3.

A sample 0.100 moles of a gas is collected at at stp. what is the volume of the gas in liters? group of answer choices 2.44 l

bearhunter [10]

n = 0.100 moles

At STP (standard temperature pressure), where gas is collected, the temperature is 0°C and the pressure is 1 atm.

$\\$\therefore$ Temperature $(T)=0^{\circ} \mathrm{C}=0^{\circ}+273$

$=273K$

$Pressure $(P)=1$ atm.$

The ideal gas equation indicates that

$\begin{aligned}& P V=n R T \Rightarrow V=\frac{n R T}{P} \\\therefore & R=\text { gas constant }=0.0821 \mathrm{~L} \cdot \mathrm{cetm} / \mathrm{mo} / \cdot K\end{aligned}$

$\begin{aligned}&V=\frac{0.100 \mathrm{~mol} \cdot \times 0.0821 \mathrm{~L} \cdot \mathrm{atm} / \mathrm{mol} . \mathrm{K} \times 273 \mathrm{~K}}{1 \mathrm{~atm}} \\&V=\frac{2.24 L}{1}\end{aligned}\\$

$V=2.24L$

Group of answer choices $2.44L$ .The volume occupied by mole of a given gas at a given temperature and pressure is expressed as the gas's molar volume.

The most typical illustration is the molar volume of a gas at STP, which is equal to $2.44L$ for $1$ mole of any ideal gas at a temperature of $273.15$ Kand a pressure of $1$ atm.

Hence, the volume of the gas is $2.24L$ .

A unit is stated to have a temperature of absolute zero $(273 Kelvins)$ and an atmospheric pressure of one atmosphere, or $1$ atm, at standard temperature and pressure. Additionally, at STP, a mole of any gas takes up $22.414 L$ of space. Keep in mind that this idea only applies to gases.

For experimental measurements to be established under standard conditions that allow for comparisons between various sets of data, standard temperature and pressure must be met.

Does a laboratory balance measure mass or weight

kolezko [41]

A balance in a lab measures the weight of a substance or object.
Weight is the mass of the body x the gravitation pull on the mass of the object.

So the mass of the object can be found by dividing the weight by gravitational constant.

The gravitational constant on earth is 1. so if a balance says that a substance weighs 300g then its mass is also 300g on earth because 300/1 = 300.

Hope that helps :)
