Answer:
-it would be too cold for humans to survive on earth

Explanation;

If greenhouse effect didn’t exist also greenhouse gases won’t exist so Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. Putting so much new CO2 into the air has made Earth warmer.

Aluminum metal reacts with bromine, a red-brown liquid with a noxious odor. The reaction is vigorous and produces aluminum bromi

GuDViN [60]

<u>Answer:</u> The mass of bromine reacted is 160.6 grams.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

Given mass of aluminium = 18.1 g

Molar mass of aluminium = 27 g/mol

Putting values in equation 1, we get:

$\text{Moles of aluminium}=\frac{18.1g}{27g/mol}=0.670mol$

The chemical equation for the reaction of aluminium and bromide follows:

$2Al+3Br_2\rightarrow 2AlBr_3$

By Stoichiometry of the reaction:

2 moles of aluminium reacts with 3 moles of bromine gas

So, 0.670 moles of aluminium will react with = $\frac{3}{2}\times 0.670=1.005mol$ of bromine gas.

Now, calculating the mass of bromine gas, we use equation 1:

Moles of bromine gas = 1.005 moles

Molar mass of bromine gas = 159.81 g/mol

Putting values in equation 1, we get:

$1.005mol=\frac{\text{Mass of bromine}}{159.81g/mol}\\\\\text{Mass of bromine}=(1.005mol\times 159.81g/mol)=160.6g$

Hence, the mass of bromine reacted is 160.6 grams.

It takes 2,267 joules of heat to raise the temperature of a 44.5 gram sample of a metal from 33.9°C to 288.3°C. What is the heat

ehidna [41]

Answer:

$\boxed{\text{0.200 J$^{\circ}$C$^{-1}$g$^{-1}$}}}$

Explanation:

The formula for the amount heat q absorbed by a substance is

q = mcΔT

where

m = the mass of the substance

C = the specific heat capacity of the material

ΔT = the temperature change

Data:

q = 2267 J

m = 44.5 g

T₁ = 33.9 °C

T₂ = 288.3 °C

Calculations:

ΔT = (288.3 - 33.9) °C = 254.4 °C

$\begin{array}{rcl}2267 & = & 44.5 \times C \times 254.4\\2267 & = & 11 180C\\C& = & \dfrac{2267}{11180}\\\\& = & \textbf{0.200 J$^{\circ}$C$^{-1}$g$^{-1}$}\\\end{array}$

$\text{The specific heat capacity of the metal is \boxed{\textbf{0.200 J$^{\circ}$C$^{-1}$g$^{-1}$}}}$

7. One mole of phosphorous pentachloride contains how many of each of the following:

RideAnS [48]

Answer:

a) 6.02 × 10^23

b)6.02×10^23

c)3.01×10^24

d) 3.612×10^24

In every mole of a substance there are 6.02×10^23 entities.

in ( c) there are 5 carbon atoms . 5 is multiplied by the number of moles of the molecule and then multiplied by 6.02×10^23. ( using the formula N=nL )
