In my opinion,
when two distinct forces are exerted in opposite directions, the resultant force is the subtraction of those forces
Therefore, 4 N - 4 N = 0 N
Response:
1. 16.54 grams.
2. 6.64 grams.
Clarification:
Greetings,
In this situation, the chemical reaction taking place is:
Thus, based on the provided data, the theoretical yield of C can be determined as:
Additionally, taking into account the principle of conservation of mass, the mass prior to the reaction is equal to the mass following the reaction, hence, the mass of B that was utilized amounts to:
Best regards.
The true statement is B. With identical masses for both metals, the final temperature of the two will be more aligned with 498 K rather than 298 K, as iron's specific heat capacity is significantly greater than that of gold's.
Cu(NO3)2 --> MM187.5558
NiNO3 *COEF2* --> 120.6983
(c) Cu + S → CuS is classified as a redox reaction
Explanation:
The following reactions are presented:
(a) K₂CrO₄ + BaCl₂ → BaCrO₄ + 2 KCl
(b) Pb²⁺ + 2 Br⁻ → PbBr₂
(c) Cu + S → CuS
Reaction (c) represents a redox reaction, as the oxidation states of the elements are changing. In this case:
Cu + S → CuS
In its elemental form, Cu has an oxidation state of 0, while in CuS (copper sulfide), its oxidation state changes to +2.
Similarly, S in its elemental form has an oxidation state of 0 and is -2 in CuS (copper sulfide).
