The electron dot diagram for an atom of carbon has how many pair(s) of electrons and how many unpaired electrons
Answer:
The resultant structure is shown below. This structure contains four shared pairs of electrons, which are located on all four "sides" of carbon's electron dot structure. Each of these shared pairs was created by pairing one of carbon's unpaired electrons with an unpaired electron from chlorine.
Explanation:
500 mL of He at 98 kPa expands to 750 mL.
500 mL of He at 98 kPa expands to 750 mL. Find P2.
P₂ = 65.3 kPa
Further explanationGiven
V₁=500 ml
P₁=98 kPa
V₂=750 ml
Required
P₂
Solution
Boyle's Law
At a constant temperature, the gas volume is inversely proportional to the pressure applied
[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]
Input the value :
[tex]\tt P_2=\dfrac{P_1.V_1}{V_2}\\\\P_1=\dfrac{98.500}{750}\\\\P_2=65.3~kPa[/tex]

Explanation:
25cm3 of a 0.4M sodium hydroxide solution was diluted into 250cm3 of water. What is the molarityof the resultant solution.
Answer:
0.04 M
Explanation:
From the question given above, the following data were obtained:
Initial volume of solution (V1) = 25 cm³
Initial Molarity of solution (M1) = 0.4 M
Final volume of solution (V2) = 250 cm³
Final Molarity of solution (M2) =?
We can obtain the final Molarity of the solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.4 × 25 = M2 × 250
10 = M2 × 250
Divide both side by 250
M2 = 10/250
M2 = 0.04 M
Therefore, the resulting molarity of the diluted solution is 0.04 M
Which periodic table trend is represented by the blue arrows?
Answer:
Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.

The measure of the speed of the moving or
vibrating particles is called the
Answer:
Temperature
Explanation:
It's called temperature.
This is because, in any substance an increase in temperature means that the particles on the average will move with greater speeds, or that they have greater kinetic energy while a decrease in temperature means that the particles on the average will move with lesser speeds, or that they have lesser kinetic energy.

A scientist thinks he found a new metal, so he published a paper about this metal. About 1 week after the scientist published the paper, you noticed a problem with the paper the scientist wrote. You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered. Using the techniques from Chemistry, you ran a Flame Test with a piece of the metal (the metal is safe to use) that you had shipped to you. You found the metal turned the flame yellow. What metal did you have in your possession?
**ANSWER CHOICES**
*Barium
*Calcium
*Strontium
*Copper
*Sodium
Answer:
Sodium

calculate the molar mass of cacl2
Answer:
[tex]\boxed {\boxed {\sf 110.98 \ g/mol}}[/tex]
Explanation:
The molar mass is the mass of a substance in grams per mole.
To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.
The compound given is:
[tex]CaCl_2[/tex]
The compound has 1 Ca (calcium) and 2 Cl (chlorine).
Mass of Calcium
The molar mass of calcium is 40.08 g/mol There is only one atom of Calcium in CaCl₂, so the number above is what we will use.Mass of Chlorine
The molar mass of chlorine is 35.45 g/mol There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2. 35.45 * 2= 70.9 g/molMolar Mass of CaCl₂
Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine. 40.08 g/mol + 70.9 g/mol =110.98 g/molThe molar mass of CaCl₂ is 110.98 grams per mole.
A 30 gram ball is at rest. Next, a force pushes the ball to the north for 2.5 seconds and the ball accelerates for a rate of 0,70 m/s/s. How fast is the ball going after the 2.5 seconds of acceleration? For credit, who work in detail
Answer:
1.75m/s or 6.3km/hr
Explanation:
here,
acceleration (a) = 0.7m/s^2
mass (m) = 30g
time (t) = 2.5s
initial velocity (u) = 0m/s
final velocity (v) = ?
now,
v = u + at
or, v = 0 + 0.7 * 2.5
hence, Final velocity (v) = 1.75 m/s
if u want to convert to km/hr
then,
1.75 * 3.6 (we know that 1m/s = 3.6km/hr)
= 6.3km/hr
