Compounds that has two elements on the formula can be bonded by ionic or covalent bond. If the compound is a metal and a non-metal then it will be ionic bonding. However, when it involves two non-metals, then it will have covalent bonding.
Cobalt-60 has 27 protons (thus 33 neutrons). If an inter-nucleus neutron decays and emits an electron, this neutron transforms into a proton. Now we have 28 protons and 32 neutrons.
When we are performing IR spectroscopy for Cyclohexane and cyclohexene, we can distinguish them as cyclohexene has C-H carbon-hydrogen stretching so, it shows the absorption at 3000-2850 cm⁻¹ range, where the cyclohexane do not have this and it shows the -C=C- stretch at 1640-1680 cm⁻¹ range in the spectrum. So that is how we can distinguish both.
The law is Newton's first law or called the law of inertia; Which just means that an object at rest stays at rest and an object in motion stays in motion and continues at the same speed and in the same direction unless acted upon by an outside force force.
Answer:
3.5 × 10³ J
Explanation:
The heat required to raise the temperature of the beer can be calculated using the following expression.
Q = c × m × ΔT
where,
Q: heat
c: specific heat capacity
m: mass
ΔT: change in the temperature
The volume of the beer is 35 mL and its density 1.2 g/mL. The mass of the beer is:
mass = volume × density
35 mL × (1.2 g/mL) = 42 g
Q = c × m × ΔT
Q = (4.186 J/g.°C) × 42 g × (20]°C - 0°C) = 3.5 × 10³ J
