Answer:
It acts as a force upon it like in newtons first law of motion an object in motion will stay in motion until a force acts upon it So friction bascicallly slows it down or stops it completly
Explanation:
Explanation:
The reaction expression is given as;
2H₂
+ O₂ → 2H₂O
From the balance reaction expression:
2 mole of hydrogen gas combines with 1 mole of oxygen gas on the reactant side;
This produces 2 mole of water on the product side of the expression.
The product is in liquid form.
This reaction is a synthesis reaction because a single product is formed from two reactants.
The hydrogenation of ethyl cinnamate will result to an ester which can be a racemic mixture of products or just a meso compound depending on the structure of the ethyl cinnamate (cis or trans). The ester will produce a frequency of C=O stretch of <span>1750 - 1735 (s.</span>
Answer:
It won't change.
-26F=3.33C
Explanation:
The pressure won't change since the system is closed and its volume is the exact same, the only way to change the tanks pressure is to open or pump more gas into or changing the temperature.
- To convert Fahrenheit to Celsius, you need to subtract 32 and divide by 1.8, in the next equation will substitute 26 F.
C=(F-32)\1.8
C=(26-32)\1.8
C=-3.33

Answer:
The answer to your question is the letter d. S
Explanation:
Data
Change of +4 in the oxidation number
Chemical reaction
K₂Cr₂O₇ + H₂O + S ⇒ KOH + Cr₂O₃ + SO₂
Process
1.- Calculate the oxidation numbers following the rules.
Some rules
H = +1 O = -2 Alkali metals = + 1 Alkali earth metals = +2
K₂⁺¹Cr₂⁺⁶O₇⁻² + H₂⁺¹O⁻² + S⁰ ⇒ K⁺¹O⁻²H⁺¹ + Cr₂⁺³O₃⁻² + S⁺⁴O₂⁻²
Elements that changed their oxidation numbers
Cr₂⁺⁶ ---------------- Cr₂⁺³
S⁰ --------------- S⁺⁴
