Answer:

a_x=4.944m/s^2

Explanation:

Hello,

Based on the acting force that is applied horizontally, one can propose the following equation based on Newton's laws:

F=ma

Nevertheless, since we've got a angled force, it becomes:

F=macos\theta

In this case, cos\theta accounts for the formed angle, so the horizontal acceleration turns out into:

a_x=\frac{F}{mcos\theta}=\frac{100kg*\frac{m}{s^2} }{25kgcos(36^0)}=4.944m/s^2

Best regads.

determine the pressure in kpa of hydrogen gas produced when 29.51g of aluminum reacts with excess sodium hydroxide and water if
Mashcka [7]

The pressure of hydrogen gas is 276.25 Kpa .

Given,

Mass of aluminum = 29.51g

Temperature (T) = 25.67 degC =298.67 K

Volume (V) = 14.75 L

The required equation when aluminum reacts with excess sodium hydroxide and water is given by ,

2Al + 2NaOH + 2H2O ==>2NaAlO2 + 3H2

molecular mass of aluminum =26.98 g

1 mole of aluminum= 26.98g

2 moles of aluminum = 53.96g

2 mole of aluminum produces =  3  moles of hydrogen gas

53.96 g of aluminum produces = 6 g of hydrogen gas

29.51 g of aluminum produces = 6*(29.51) /53.96 =3.28 g of hydrogen gas

Thus ,

2 g of hydrogen gas = 1 mole of hydrogen

3.28 g of hydrogen gas = 3.28/2 mole =1.64 mol of hydrogen

Thus , n = 1.64 mol

According to ideal gas equation ,

PV=nRT

P=nRT/V

P = 1.64 * (0.0821L atm K^-1mol^-1 ) *(298.67 K)/14.75L

P=2.726 atm

P= 276.25 Kpa

Hence the pressure of hydrogen gas is 276.25 Kpa .

A student has a 1g sample of each of the following compounds: NaCl, KBr, and KCL Which of the following lists the samples in ord
krek1111 [17]

Given :

A student has a 1 g sample of each of the following compounds: NaCl, KBr, and KCl.

To Find :

The samples in order of increasing number of moles in the sample.

Solution :

Molecular mass of NaCl, KBr, and KCl is 58.5 g/mol , 119 g/mol and

74.5 g/mol respectively .

Moles of NaCl , n_1=\dfrac{1}{58.5}=0.017\ mol.

Moles of KBr , n_2=\dfrac{1}{119}=0.008\ mol.

Moles of KCl , n_2=\dfrac{1}{74.5}=0.013\ mol.

The order of moles in increasing order is :

KBr , KCl and NaCl .

Hence , this is the required solution .
