Slav-nsk [51]

Answer:

A.

Explanation:

Power is measured in Watts, and can we calculated by taking the work done in joules / the time in seconds. Thus, 1 Watt is 1 joule per 1 second (1 Watt = 1J/s)

To begin the experiment, a bomb calorimeter is filled with 1.11 g CH4 and an excess of oxygen. The heat capacity of the calorime
Flura [38]
There are several information's already given in the question. Based on those information's the answer can be easily determined.

M = <span>1.11 g CH4
C = </span>4.319 kJ g C⋅°
∆T = 35.65 - 24.85 degree centigrade
     = 10.8 degree centigrade.
Then
∆H =−M ⋅ C ⋅∆T
      = - 1.11 * 4.319 * 10.8
      = - 51.776 kJ/<span>mol

I hope the procedure is clear enough for you to understand.</span>

How many moles of silane gas (SiH4) are present in 8.68 mL<br> measured at 18 0C and 1.50 atm?
makvit [3.9K]

Answer:

5.45*10⁻⁴ moles of silane gas (SiH₄) are present in 8.68 mL  measured at 18°C and 1.50 atm.

Explanation:

An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P * V = n * R * T

In this case:

  • P= 1.5 atm
  • V= 8.68 mL= 0.00868 L (being 1000 mL= 1 L)
  • n= ?
  • R= 0.082 \frac{atm*L}{mol*K}
  • T= 18 C= 291 K (being 0 C= 273 K)

Replacing:

1.5 atm* 0.00868 L= n* 0.082\frac{atm*L}{mol*K} *291 K

Solving:

n=\frac{1.5 atm*0.00868 L}{0.082 \frac{atm*L}{mol*K}*291 K}

n= 5.45*10⁻⁴ moles

<u><em>5.45*10⁻⁴ moles of silane gas (SiH₄) are present in 8.68 mL  measured at 18°C and 1.50 atm.</em></u>

Consider the following statements about weeding and identify the incorrect one.
dolphi86 [110]

Answer:

b) Weeding is the process of growing weed

Explanation:

Wedding is an agricultural process carried out to ensure maximum you won't do. It is the process by which weeds i.e. unwanted plants are removed.

As rightly stated in the question;

- Weeding is either done by manual means e.g Cutlasses or use of weedicides, which are chemicals.

- Weeding is best done during tiling operations.

The incorrect option is that "Weeding is the process of growing weed" rather it is a process of removing weed.
