A push is a force that moves an object away from something.
Therefore your baby sister is using a push force.
I would use the following steps:
- Write the <em>balanced chemical equation</em> for the reaction.
- Use the molar mass to <em>convert the mass of the reactant to moles</em>.
- Use the molar ratio of product:reactant from the balanced chemical equation to <em>convert moles of reactant to moles of product</em>.
- Use the molar mass of the product to <em>convert moles of product to mass of product</em>.
You can use the diagram below to remind you of the importance of the <em>molar ratio</em> in mass-mass conversions
You must get over the mole “hill” to make the conversion.
The number of protons an element has is the same as the atomic number, so the element would have 86 protons.
B. Fungi are heterotrophs and plants are autotrophs
Answer:
the partial pressure of Xe is 452.4 mmHg
Explanation:
Dalton's law of partial pressures says that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.
The partial pressures can be calculated with the molar fraction of the gas, in this case, Xe.
Molar fraction of Xe is calculated as follows:
Then, 0.29 is the molar fraction of Xe in the mixture of gases given.
To know the parcial pressure of Xe, we have to multiply the molar fraction by the total pressure:
Partial Pressure of Xe=1560mmHg*0.29
Partial Pressure of Xe=452.4mmHg
