A heated metal object whose temperature is 50 °C is dropped into
a tub of water whose temperature is 0°C. What will happen to the
temperature of the metal and water after 5 minutes?
answer: the oject would break because of the amount of cooling added to the mass so after five minutes it would start to crust a little bit. and the temprature would decrese jarastically

What is primarily released in radioactive decay?
Answer:
When radioactive atoms decay, they release energy in the form of ionizing radiation (alpha particles, beta particles and/or gamma rays). The energy is called ionizing radiation because it has enough energy to knock tightly bound electrons from an atom's orbit. This causes the atom to become a charged ion.

Complete the mechanism for the reaction of butanone with NaBH4 followed by the addition of aqueous acid. Butanone is a 4 carbon chain where carbon 2 is double bonded to oxygen. This reacts with N a B H 4, followed by H 3 O plus to give the final product. Step 1: draw curved arrows. ⟶ Step 2: Draw the charged organic intermediate product. Include nonbonding electrons and charges. Omit the counterion. −→−−H3O+ Step 3: Draw the final product
The formation of a primary alcohol from a ketone involves the use of a ketone and NaBH4 followed by an acid workup.
Formation of a primary alcoholThe question is unclear but clearly relates to the formation of a primary alcohol. The first step in this reaction is the attack of the NaBH4 on the carbonyl carbon of butanone.
The reaction sequence is completed by an acid work up in which an acidic hydrogen is abstracted by the nucleophile to yield a primary alcohol.

Scientific laws commonly answer which questions about the world?
1. Why?
2. How?
3. How many?
4. What?
Answer:
How
Explanation: In science a person has to be curious on how things work. Key word how. Why makes sense but how is the better answer. How many is a specific question. But it doesn't involve the whole spectrum of science. What also doesn't make sense.
A scientific law is a proposition that states what consistently takes place under specific circumstances. The law of conservation of mass and the law of conservation of energy are two other examples of physical science laws. The correct option is 2.
A scientific law only describes an occurrence in the natural world; it makes no attempt to explain how it happens. It is only the outcome of several observations and is supported by empirical evidence.
The definition of a naturally occurring phenomenon in the world is scientific law. It clarifies how something occurs. Equations or formulas in mathematics are used to express laws.
Thus the correct option is 2.

Which hydrogen of 1-chloropent-2-ene shows the largest chemical (downfield) shift in its nmr spectrum?
The hydrogen of 1-chloropent-2-ene shows the largest chemical shift is C2 or C3 because they are more de-shielded than they have the largest chemical shift value.
Which hydrogen of 1-chloropent-2-ene shows the largest chemical shift in its nmr spectrum?Generally, There is the biggest chemical shift at C2 or C3 due to the fact they are connected through the pi- bond and range is about 4.5 - 6 ppm and C1 has a range of about 3.5 due to Cl- ion.
In conclusion, C2 or C3 is more de-shielded than they have the largest chemical shift value.

What is the ph of a solution of h2so4 that has [h3o ] = 5.45 × 10–5 m? round to the nearest hundredth.
The pH of a solution of H₂SO₄ that has [H₃O⁺] is 5.45 × 10⁻⁵ M, is 4.26.
What is pH?pH is define as the negative logarithm of the concentration of H⁺ or H₃O⁺ ions, and it is represented as:
pH = -log[H⁺]
Concentration of H₃O⁺ in H₂SO₄ solution = 5.45 × 10⁻⁵ M
pH of H₂SO₄ solution will be calculated as:
pH = -log(5.45 × 10⁻⁵)
pH = -(-4.26)

What causes “gaps in the rock record” and how is that described?
Answer:
An unconformity is a widespread surface separating rocks above and below, which represents a gap in the rock record. Unconformities occur when either erosion wears away rocks, or rock deposits never form. Therefore, a time gap exists between when the rocks below the unconformity formed and when those above it formed.
