Answer:
Alkane
Explanation:
Alkane is a class of organic compounds that contain only carbon and hydrogen and the carbon atoms are connected to each other by single bonds.
Now, if we look at the molecule whose condensed structural formula is shown in the question, we will notice that the compound can only contain single bonds. That is, the molecule is a saturated hydrocarbon(alkane).
I have drawn out the full structure of the compound to illustrate this point.

How many moles are in 74.8 grams of NaCl?
Answers
Answer:
1.28 mol NaCl
Explanation:
Find the mass of NaCl by adding the two elements atomic mass
Na: 22.99
Cl: 35.45
22.99+35.45=58.44 g
Now convert to moles
74.8 g / 58.44 g = 1.27994524298 mol

The kinetic energy of the ionized electron is measured to be 15.2 eV and the kinetic energy of the proton produced from the ionization of hydrogen is 4.3 eV. What would be the final kinetic energy of the projectile proton after the collision
Answers
Answer:
Explanation:
Ionization energy of hydrogen atom is 13.6 eV . This energy will be provided by energetic proton , the kinetic energy of which is 1000 eV. The kinetic energy of ionized electron is 15.2 eV . Kinetic energy of proton produced from from the ionization of hydrogen or the nucleus of the hydrogen atom is 4.3 eV . All these energy must have come from kinetic energy of initial proton.
So kinetic energy of projectile proton after collision
= 1000 - ( 13.6 + 15.2 + 4.3 ) eV.
= 966.9 eV .

What is the concentration of sodium ions in 0.185 M Na2CO3?
Answers
Answer:
0.370 M
Explanation:
Step 1: Given data
Molar concentration of the sodium carbonate solution: 0.185 M
Step 2: Write the balanced dissociation equation
Sodium carbonate is a strong electrolyte that dissociates according to the following equation.
Na₂CO₃(aq) ⇒ 2 Na⁺(aq) + CO₃²⁻(aq)
Step 3: Calculate the molar concentration of sodium ions
The molar ratio of Na₂CO₃ to Na⁺ is 1:2.
0.185 mol Na₂CO₃/L × 2 mol Na⁺/1 mol Na₂CO₃ = 0.370 mol Na⁺/L

Jewelry and tableware are sometimes made of sterling silver. Sterling silver is 92.5% silver (Ag) and 7.5% copper (Cu). If you wanted to make 30 grams of sterling silver for a ring, how many grams of silver and copper would you need to start with?
Amount of sterling silver?
Amount of copper?
total grams of alloys needed?
Answers
Answer:
12.33
Explanation:
92.5/7.5= 12.33
30g of the sterling silver ring contains, 27.75 g of silver and 2.25 g of copper.
What is cross multiplication?Cross multiply fractions by multiplying one fraction's denominator by the other fraction's numerator and then comparing the two values. The larger fraction is the one with the higher value.
100g of sterling silver contains 92.5g of silver and 7.5g of copper.percentage of element = amount of the element present in 100 g of materialTherefore,
100g sterling silver = 92.5g silver30g sterling silver = X g silver( cross multiplication),
100 × X = 92.5 × 30
X = 92.5 × 30/ 100
X= 27.75g silver100g sterling silver = 7.5g copper
30g sterling silver= Y g copper
(cross multiply)
100 × Y = 7.5 × 30
Y= 7.5 × 30 / 100
Y= 2.25g copperX (silver)= 27.75 g in 30 g of sterling silverY (copper)= 2.25 g in 30 g of sterling silvertherefore, 30g of sterling silver ring contains, 27.75 g of silver and 2.25 g of copper.

Answer: [tex]H_2[/tex] < [tex]CO[/tex] < [tex]O_2[/tex] < [tex]CO_2[/tex] < [tex]CL_2[/tex]
Explanation:
According to avogadro's law, 1 mole of every substanceweighs equal to its molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
1. Mass of [tex]H_2=moles\times {\text {Molar mass}}=0.50moles\times 2g/mol=1g[/tex]
2. Mass of [tex]O_2=moles\times {\text {Molar mass}}=0.50moles\times 32g/mol=16g[/tex]
3. Mass of [tex]Cl_2=moles\times {\text {Molar mass}}=0.50moles\times 71g/mol=35.5g[/tex]
4. Mass of [tex]CO_2=moles\times {\text {Molar mass}}=0.50moles\times 44g/mol=22g[/tex]
5. Mass of [tex]CO=moles\times {\text {Molar mass}}=0.50moles\times 28g/mol=14g[/tex]
Thus the flasks of gases in order of increasing grams of gas is:
[tex]H_2[/tex] < [tex]CO[/tex] < [tex]O_2[/tex] < [tex]CO_2[/tex] < [tex]CL_2[/tex]
