Answer:

Explanation:

When  drawing lewis dot  diagram  structure  we  consider the  number  of  valence electrons  of  the atom.Se  has  six valence electrons since  it  is  in  group  six thus  it Lewis  dot diagram  is  as  follows

      ..

    : Se:

Hydrogen  is  in  group  one  hence  has  one  valence  electron.The  lewis dot  diagram  for  2H is  therefore

mars1129 [50]

Molar mass of butane = 12g/mol*4+1g/mol*10=58g/mol

Mass of 2 moles of butane=2mol*58g/mol=116g

2c4h10(g)+13o2(g)->8co2(g)+10h2o(l)

<span>116g                        8 moles</span>

<span>3.20g                           x</span>

 

116g butane/8moles CO2=3.20g butane/x

x=3.20g butane*8moles CO2/116g butane=0.2207moles CO2

T=23°C=296K

PV=nRT

V=nRT/P=0.2207moles*0.082(atm*dm³/(K/mol))*296K/(1atm)=5.36dm³

1. What is the mass of 22.4 L of H2 at STP?
Fed [463]
1.
n = m/2.016 g/mol = V/22.4 l
V = 22.4 l
Hence,
m = 2.016 g ≈ 2.02 g
B.) 2.02 g

2.
Balancing the equation, we get,
Mg + 2HCl → MgCl2 + H2
PV = nRT
V = nRT/P
V = 1.5 mol × 8.314 atm/(mol.K) × 298 K/(0.96 atm)
V = 3871.206
V ≈ 38.2 l

The figure shows a graph of Allison’s walk to school. She follows the black vectors to get to her school. Which if the following
Lubov Fominskaja [6]

Answer:

Allison walks 5 blocks west and 3 blocks south.

Explanation:

Vectors have both magnitude and direction. The attached figure shows the graph of Allison’s walk to school. She follows the black vectors to get to her school.

The first vector on the horizontal axis points towards west and there are 5 blocks. Initially, she walks 5 blocks in west direction.

The second vector points in the negative vertical axis. It means that she walks  3 block in south direction.

Hence, the correct option is (D) i.e. Allison walks 5 blocks west and 3 blocks south.

What is the [h+] concentration in a urine sample that has a ph of 6?
NISA [10]
<h3>Answer:</h3>

           1.0 × 10⁻⁶ M       (Option-A)

<h3>Solution:</h3>

Data Given:

                  pH  =  6

                  [H⁺]  =  ?

Formula Used:

As we know pH is given as,

                                  pH  = -log [H⁺]

and,

                                  [H⁺]  =  10^-pH    ----- (1)

Putting value of pH in eq. 1,

                                  [H⁺]  =  10⁻⁶                                       ∴ 10  =  Antilog

                                  [H⁺]  =  1.0 × 10⁻⁶ M
