Answer:
Gjvb
Explanation:
Using the combined gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (kPa)
P2 = final pressure (kPa)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to this question;
T1 = 300K
T2 = -73 + 273 = 200K
P1 = 303kPa
P2 = 202kPa
V1 = 2L
V2 = ?
Using the above formula:
303 × 2/300 = 202 × V2/200
606/300 = 202V2/200
Cross multiply;
606 × 200 = 300 × 202V2
121200 = 60600V2
V2 = 121200/60600
V2 = 2L
The new volume is 2L
Answer:
carbon
Explanation:
tbh im not sure just guessing
I would start by converting g/mL to g/L
75.00g/1000.0mL = 75.00g/L
Stoichiometrically, flip 75 onto the bottom so that grams cancel out and we are left with the number of L required.
(L/75.00g)(15g) -> this is essentially dividing 15g by 75g, which cancels the unit g, leaving us with 0.2L. If the question requires an answer in mL, just multiple the number of L by 1000.
The patient requires 200mL of glucose solution to receive his 15g of glucose.
So that other scientist can repeat their experiments
i hope i got i right
An c.ionic bond forms when a cation transfers its extra electron to an anion who needs it.
For example compound magnesium chloride (MgCl₂) has ionic bond (<span>the </span>electrostatic attraction<span> between oppositely charged </span><span>ions)</span>. Magnesium transfers two electrons (became positive cation) to chlorine (became negative anion).
