Answer:

Phenylmethanethiol

Explanation:

Benzyl bromide is a compound from the toluene family with an alpha position substituent of bromine. When this compound (Benzyl bromide) reacts with sodium hydrogen sulfide, it yields a principal organic product called Phenylmethanethiol which is an alpha-toluenethiol that belongs to a group of aromatic compounds containing one monocyclic ring system comprising of benzene.

Answer:

Cakes, breads and other foods that contain leavening agents rise more quickly at higher altitudes, because gases produced by the agents expand faster than at sea level. The loaves may collapse if the gases dissipate before the proper temperature is reached. Most baking recipes can be adjusted for high altitudes.

Answer:

The volume of NaOH used

Explanation:

The tip of the buret is part of its calibration. If this tip is not filled before taking the initial reading, the volume of NaOH used at the end of the titration would be inaccurate.

In order to avoid this, the valve of the buret should be opened and the NaOH allowed to displace whatever air that might have been trapped at the tip before the initial buret reading is taken and the titration is carried out.

Answer:

Mass of Hydrogen atoms : 18 g

Given

73 gram of HCl

144gram of H₂O

Required

Mass (gram) atom of Hydrogen

Solution

H atoms are in 2 compounds, H₂O and HCl, so we calculate their mass in each compound

[tex]\tt \dfrac{1}{36.5}\times 73=2~g[/tex]

mass H in HCl :

[tex]\tt \dfrac{2}{18}\times 144=16~g[/tex]

total mass = 2 g+ 16 g = 18 g

Answer:

Avogadro's number is 6.022×1023 molecules. With Avogadro's number, scientists can discuss and compare very large numbers, which is useful because substances in everyday quantities contain very large numbers of atoms and molecules.

Answer:

correct

Explanation:

Answer:

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Where's the question?

Answer:

1. C. thunderstorm

2. D. can trap polluted air causing health problems

3. C. mesocyclone

4. B. a cyclone

Explanation:

A temperature inversion happens as a result of warm air developing over a layer of cooler air.

A thunderstorm is a violent weather with strong winds, lightning, thunder, heavy rain fall and dense clouds. This occurs when warm air rise in an updraft to cooler atmosphere.

Answer:

1. Thunderstorm  

2.can trap polluted air causing health problems

3.mesocyclone

4.typhoon in the northern hemisphere

Explanation:

Answer:

V = 146.87 L

Explanation:

Given data:

Mass of sample = 14.0 g

Pressure of sample = 120 kpa

Volume of gas = ?

Temperature of gas = 30°C

Solution:

Number of moles of gas:

Number of moles = mass/molar mass

Number of moles = 14.0 g/ 2 g/mol

Number of moles = 7 mol

Pressure of gas:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 8.31 KPa.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

30+273 = 303 K

by putting values,

120 KPa × V = 7 mol × 8.31 KPa.L/ mol.K  × 303 K

V = 17625.51 KPa .L/ 120 KPa

V = 146.87 L

Answer:

The fraction is 6/7

Explanation:

6/7 is the simplified fraction for 54/63 by using the GCD or HCF method. Thus, 6/7 is the simplified fraction for 54/63 by using the prime factorization method.

Can I have Brainliest???

Answer:742 torr= approximately 0.976 atm

Explanation:

Since we know that one atm= 760 torr, we can compute the following calculation:

(742 torr/1)*(1atm/760torr)=0.976316 atm

Remember sig figs (3) to round it to 0.976 atm

[tex]\frac{742 torr}{1}[/tex]*[tex]\frac{1 atm}{760 torr}[/tex]=0.976316=0.976 atm

(torr cancels out and we're left with atm)

Explanation:

Explanation:

Molar mass of CaCl2 = 110.98g/mol

Moles of CaCl2 = 30.0 / 110.98 = 0.270mol

Moles of AgCl = 0.270mol * 2 = 0.540mol

Mass of AgCl = 0.540mol * (143.32g/mol) = 77.39g.

Answer:

77.5

The volume of the bag would be in (L) upon arrival in Whistler : 0.66

Boyle's Law  

At constant temperature, the gas volume is inversely proportional to the pressure applied  

[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

V₁=0.51 L

P₁=1.01 atm

P₂=0.78 atm

[tex]\tt V_2=\dfrac{P_1.V_1}{P_2}\\\\V_2=\dfrac{1.01\times 0.51}{0.78}\\\\V_2=0.66[/tex]

Answer:

measuring the consumption of the products and the rate of conversion of products to reagents

Explanation:

It must be taken into account that the reaction rate also depends on the presence of a catalyst, since these advance the rate of the reaction.

Answer:

NH3(aq) + HNO3(aq) → NH4NO3(aq) Calculate the volume of an acid (1.5 M HNO3) needed to neutralize the 1.5 M HNO3.

Explanation:

Answer:

The law of conversion of mass is a scientific law that says that mass or matter can not be created or destroyed like energy but changes its form in a different type of state. So, by the law of conversion of mass, you can say that mass is not disappeared but change in different forms of states of matter like gas, soot, or melted residues of candle and ash of thread.

Due to this, the mass of the solid or waxy state due to burning changes to gas released by burning and residue of wax that will be equal to the mass of the original mass.
