IAL is the suffix pertaining to conditions percent are birth.
Answer:
A)3410K
B)5678.6 °F
Explanation:
✓ To convert Celcius to Kelvin expression below can be used
K= °C + 273
We were given T=3137 °C
= 3137 + 273= 3410K
✓To convert Celcius to Fahrenheit, expression below can be used
°F =(°C × 9/5) + 32
We were given T=3137 °C
°F= (3137 × 9/5) + 32
= 5646.6+32
=5678.6 °F
Answer:
B
Explanation:
The temperature is proportional to the kinetic energy of the system.
The kinetic energy is a measure of the movement capability of the molecules of the system. Hence, we can directly say molecules moving faster possess more average kinetic energy.
This kinetic energy is a measure of temperature. This is in the sense that the higher the temperature, the higher the degree of turbulnece . This tends to show us that the molecules are moving with greater speed.
Hence, we can conclude that there is a direct degree of proportionality between the temperature and the kinetic energy of the molecules as an increase in temperature causes a corresponding increase in the speed of the molecules
Basically, an element<span> is made of only one kind of atom, while a </span>compound<span> contains the atoms of two or more </span>elements<span>.
Just to give you a good exaple:
Gold is made of only one kind of atom, so it's considered an </span>element<span>, but water is a mix of hydrogen and oxygen, so it's a </span>compound<span>.</span>
Answer:
12.9 g O₂
Explanation:
To find the mass of oxygen gas produced, you need to (1) convert grams KClO₃ to moles KClO₃ (via molar mass from periodic table values), then (2) convert moles KClO₃ to moles O₂ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles O₂ to grams O₂ (via molar mass). It is important to arrange the conversions/ratios in a way that allows for the cancellation of units (the desired unit should be in the numerator). The final answer should have 3 sig figs to match the given value (33.0 g).
Molar Mass (KClO₃): 39.098 g/mol + 35.45 g/mol + 3(15.998 g/mol)
Molar Mass (KClO₃): 122.542 g/mol
2 KClO₃ ---> 2 KCl + 3 O₂
Molar Mass (O₂): 2(15.998 g/mol)
Molar Mass (O₂): 31.996 g/mol
33.0 g KClO₃ 1 mole 3 moles O₂ 31.996 g
-------------------- x ------------------- x ----------------------- x ------------------ =
122.542 g 2 moles KClO₃ 1 mole
= 12.9 g O₂
