How many reactants are there?
DONE
Answers
Answer:
1
Explanation:
By observing the appearance (colors, textures, etc.) of the reactants in the data one reactant is there.
What is reactant?A reactant is a substance or can say a chemical compound that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products.
For example we take a reaction-
O₂(g) + H₂(g) → H₂O(g)
Here, O₂ and H₂ are the reactants and H₂O is the product.
A reactant is present 100% initially and after sometimes it reduces gradually to form product according to chemical kinetics.
Given, the picture shown and the colour and texture of the reactant is shown.
Therefore, By observing the appearance (colors, textures, etc.) of the reactants in the data one reactant is there.

calculate the molar mass of cacl2
Answers
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.

Which periodic table trend is represented by the blue arrows?
Answers
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.

Answer:
hope this document helps! it's kinda hard to type out the explanation but ill try
Explanation:
divide the percenatge by the molar mass of the element.
(do this for both elements) \
find the lowest number and divide the results with it
now you have your empirical formula (with the rounded answers)
then find the molar mass of your empirical formula
divide the number given (267) by the molar mass to get a rounded number.
multiply that rounded answer to your empirical formula to get your empirical formula. :)

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
Answers
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
1. A 50 gram sample of a radioisotope decays to 12.5 grams in 14.4 seconds. What is
the half-life of this isotope?
Answers
Answer:
Half life = 7.2 seconds
Explanation:
[tex]from \: decay \: equation \\ 2.303 log( \frac{n.}{nt} ) = kt \\ 2.303 log( \frac{50}{12.5} ) = k \times 14.4 \\ k = \frac{2.303 log( \frac{50}{12.5} )}{14.4} \\ k = 0.096288 {s}^{ - 1} \\ since \: half \: life = \frac{ ln(2) }{k} \\ half \: life = \frac{ ln(2) }{0.096288} \\ half \: life = 7.2 \: seconds[/tex]
That will work with all of those problems
