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>:
It is a covalent bond. Whenever a compound uses such suffixes like mono, di, tri, tetra, and so on, it is a covalent compound- thus having covalent bonds.
Explanation:
0.00208 is the correct standard form
Answer:
There are four ways to find the charge of an element:
Use the periodic table. The usual charge of an element is common to its group. ...
Use a chart. ...
For a single atom, the charge is the number of protons minus the number of electrons.
Find the charge by balancing charge in a compound
0.15*240=36 ml of alcohol in <span>240 ml of a 15% alcohol mixture
0.4x = </span>ml of alcohol in x ml of a 40% alcohol mixture
0.2(x+240)= ml of alcohol in (x+240) ml of a 20% alcohol mixture
0.15*240 + 0.4x = 0.2(x+240)
36+0.4x=0.2x+48
0.2x = 12
x=12/0.2=120/6=20 ml of a 40% alcohol mixture
