Answer:

Mechanical advantage = load/<u>effort</u>

Explanation:

Mechanical advantage is like a ratio of load to effort and many machines like pulleys depend on this relationship between load and effort for it to work.

Answer:

The formula of mechanical advantage is Load÷effort

Explanation:

Mechanical advantage is the ratio of the load to the effort i.e. MA=Load(L)÷Effort(E)

What is the empirical formula of a carbon-oxygen compound, given that a 95.2 g sample of the compound contains 40.8 g of carbon

algol [13]

Answer:

95.2 - 40.8 = 54.4 g of oxygen

number of moles = mass (g)/ Mr

no. of moles of carbon = 40.8/12 = 3.4

no. of moles of oxygen = 3.4

divide both by smallest value which is 3.4 and you’ll get 1 mole of carbon and 1 mole of oxygen therefore the empirical formula is CO

hope this helps :)

When the pressure that a gas exerts on a sealed container changes from 22.5 psi to psi the temperature changes from 110 c to 65.

ad-work [718]

Gay- Lussacs law states that the pressure of a gas is directly proportional to temperature for a fixed amount of gas at constant volume.
therefore P/T = k
where P - pressure , T - temperature and k - constant
$\frac{P1}{T1} = \frac{P2}{T2}
$
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - temperature in kelvin - 110 °C + 273 = 383 K
T2 - 65.0 °C + 273 = 338 K
substituting these values in the equation

$\frac{22.5 psi}{383 K} = \frac{P}{338K}$
P = 19.9 psi
new pressure is 19.9 psi

Calculate the pressure (in kpa) of 1.5 mole of helium gas at 354 k when it occupies a volume of 16.5l.

3241004551 [841]

Answer:

267.57 kPa

Explanation:

Ideal gas law:

PV = n RT R = 8.314462 L-kPa/K-mol

P (16.5) = 1.5 (8.314462)(354) P = 267.57 kPa

what is the difference between a chemical bonds formed in the molecules of 02 and the chemical bonds formed in crystals of a NaC

Jobisdone [24]

Answer:

O2 is a covalent substance while NaCl is an ionic substance

Explanation:

In O2 molecule, the bond is between 2 oxygen atoms which are non - metals. Thus, this is a covalent bond since it involves 2 non metals.

Whereas, for the NaCl molecule, the bond is between a metal sodium (Na) and a non metal Chloride(Cl) and thus we can say this is an ionic bond.

Thus the difference is that O2 is a covalent substance while NaCl is an ionic substance.
