Answer:
263 K
Explanation:
Assuming ideal behaviour and constant pressure, we can solve this problem by using Charles' law, which states that at constant pressure:
In this case:
We <u>input the data</u>:
- T₁ * 824.7 mL = 377 K * 575.45 mL
And <u>solve for T₁</u>:
Answer:
C. H:C:H:H
Explanation:
Follow these simple steps to correctly draw a Lewis dot structure: Add up the total number of valence electrons found in the entire compound. Draw the simple structure (skeleton structure) of the compound by connecting everything with single bonds only. Add electrons to all the noncentral atoms. Put any unused electrons on the central atom.
1. 2650000
2. 2410
3. 48100
Answer:
Molar masses of X and Z
Explanation:
To determine the mole percent of a mixture ( mole percent of unknown metals = number of mole of each of them divided the total of both the unknown salt × 100) since the percent by mass is know; we the molar mass of X and Z
mole = mass given / molar mass
