The chemical formula for glucose (sugar) is C6H12O6. What are the individual numbers called in a chemical formula?
givi [52]

The individual numbers which are present in chemical formula is subscript.

<h3>What is chemical formula?</h3>

Chemical formula of any compound of chemistry consist more than one atoms in it and gives idea about the number of atoms present in that compound.

Given chemical formula of glucose is C₆H₁₂O₆.

In the given chemical formula of glucose, number which shows the amount of carbon, hydrogen and oxygen are known as subscripts.

Hence, individual number are subscript.

A scuba tank has a pressure of 195 KPa at a temperature of 10 °C. The volume of the tank is 350 L. How many grams of air is in t
marissa [1.9K]

The mass of air in the scuba tank is 841.614 g.

Using the ideal gas equation;

PV=nRT

P = pressure of the gas = 195 kPa

V = volume of the gas =  350 L

n = Number of moles of the gas = ??

R = molar gas constant = R = 8.314 J K-1 mol-1

T = temperature of the gas =  10 °C or 283 K

n = PV/RT

n = 195 * 350/8.314 * 283

n = 68250/2352.862

n = 29.00 moles

Number of moles = mass/molar mass

mass of air = Number of moles * molar mass

mass of air = 29.00 moles * 29g/mol

Mass of air = 841.614 g

2. ATO kg bouting ball would require what force to accelerate down an alleyway at a rate of ons?
Mars2501 [29]

Answer:

  • 2. 30N
  • 3. 5,000N
  • 4. 15 kg
  • 5. 2,800 kg

Explanation:

<em>2. A 10 kg bowling  ball would require what force to accelerate down an alleyway at a rate of 3m/s² ?</em>

Notice that I completed the question with the garbled and missing values:

<u>Data:</u>

  • F = ?
  • m = 10 kg
  • a = 3m/s²

<u />

<u>Physical principles:</u>

  • Newton's second law: F=m\times a

<u>Solution:</u>

  • Substitute and compute

        F=10kg\times 3m/s^2=30N

<em></em>

<em>3. Salty has a car that accelerates at 5 m/s². If the car has a mass of 1000 kg, how much force does the car produce?</em>

Notice that I arranged the typos.

<u />

<u>Data:</u>

  • F = ?
  • m = ?
  • a = ?

<u>Physical principles:</u>

  • Newton's second law: F=m\times a

<u>Solution:</u>

  • Substitute and compute

       F=1,000kg\times5m/s^2=5,000N

<em>4. What is the mass of a falling rock if it produces a force of 147 N?</em>

<u>Data:</u>

  • F = 147N
  • m = ?
  • a = falling rock

<u>Physical principles:</u>

  • neglecting air resistance ⇒ a = g: gravitational acceleration: 9.8m/s²
  • Newton's second law: F=m\times a

<u>Solution:</u>

  • Clear m from Newton's second law

         m=\dfrac{F}{a}

  • Substitute with F = 147 N and a = g = 9.8m/s², and compute

      m=\dfrac{147N}{9.8m/s^2}=15Kg

<em></em>

<em>5. What is the mass of a truck if it produces a force of 14,000 N while accelerating at a rate of 5 m/s²?</em>

<u>Data:</u>

  • F= 14,000N
  • m = ?
  • a =​ 5m/s²

<u>Physical principles:</u>

  • Second Newton's law: F=m\times a

<u>Solution:</u>

  • Clear m from Newton's second law

         m=\dfrac{F}{a}

  • Substitute with F = 14,000 N and a = 5m/s², and compute

      m=\dfrac{14,000N}{5m/s^2}=2,800kg
