Explanation:
Reaction type : Double-Replacement reactions
<h3>Further explanation</h3>
Given
Reaction
MgCl2 +
Li2CO3 →
MgCO3 +
LiCl
Required
Balanced equation
Reaction type
Solution
Balanced equation
Li2CO3 (s) + MgCl2 (aq) → MgCO3 (s) + 2 LiCl (aq)
Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product
To predict whether this reaction can occur or not is one of them, the precipitation reaction.
MgCO3 is a precipitation compound
Answer:
![V_2=2.5m^3](https://tex.z-dn.net/?f=V_2%3D2.5m%5E3)
Explanation:
Hello!
In this case, according to the Charles' law as a directly proportional relationship between volume and temperature:
![\frac{V_2}{T_2}=\frac{V_1}{T_1}](https://tex.z-dn.net/?f=%5Cfrac%7BV_2%7D%7BT_2%7D%3D%5Cfrac%7BV_1%7D%7BT_1%7D)
Thus, in order to compute the final volume, V2, we obtain the following expression:
![V_2=\frac{V_1T_2}{T_1}\\\\V_2=\frac{5m^3*300K}{600K}\\\\V_2=2.5m^3](https://tex.z-dn.net/?f=V_2%3D%5Cfrac%7BV_1T_2%7D%7BT_1%7D%5C%5C%5C%5CV_2%3D%5Cfrac%7B5m%5E3%2A300K%7D%7B600K%7D%5C%5C%5C%5CV_2%3D2.5m%5E3)

<h2>Answer : Option A) 2540 g</h2><h3>Explanation : </h3>
Here, the density of the gelatin is known to be as 1.27
.
And the volume 2.0 liter
Here, 2 liters = 2
so to convert it into
we have to multiply it, with 1000 to 2000
,
Using, the formula for density;
ρ =
Here,
ρ = density;
m =mass and v=volume.
Substituting the values given; ρ = 1.27 ![g/cm^{3}](https://tex.z-dn.net/?f=g%2Fcm%5E%7B3%7D)
m = to be found and v = 2000 ![centimetres^3](https://tex.z-dn.net/?f=centimetres%5E3)
ρ =
1.27
= m X 2000 ![centimetres^3](https://tex.z-dn.net/?f=centimetres%5E3)
m = 2540 g
Therefore, the mass will be 2540 g
Answer is: <span>5. one pair of electrons and two lone electrons.
Electron configuration for carbon: </span>₆C 1s² 2s² 2p².
Valence electrons are in 2s and 2p orbitals. There is one pair of electrons in 2s orbital and two lone electrons in 2p orbital with the same electron spin. Carbon is in group 14 of periodic table group.
