Correct Answer: option 1 i.e. C
Reason:
The the compound of interest i.e. XCl4, since there are 4 Cl atoms bonded to X. This signifies that the valency of X is 4.
There atomic number of C is 6. It's electronic configuration is giving by 1s2 2s2 2p2. Thus, there are 4 electrons in valence shell of C. This signifies that valency of C is 4. Hence the compound present in present case is CCl4.
Answer:
Explanation:the best guess I will go with is H but I might be wrong
In artificial transmutations the nucleus is bombarded with high-energy (kinetics energy) particles to induce transmutation. There are two reactants or the nucleus that is being bombarded and the high-energy particle.
<span>High-energy particles are accelerated in accelerators, by the application of electric and magnetic fields. Neutrons cannot be accelerated in accelerators using electric and magnetic fields because their charge is 0.
I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:
The mass of 10 cm³of a 0.4 g/dm³ solution of sodium carbonate is 0.004 grams
Explanation:
The question is with regards to density calculations
The density of the given sodium carbonate solution, ρ = 0.4 g/dm³
The volume of the given solution of sodium carbonate, V = 10 cm³ = 0.01 dm³


Therefore, we have;

The mass, "m", of the sodium carbonate in = ρ×V = 0.4 g/dm³ × 0.01 dm³ = 0.004 g
The mass of 10 cm³ (10 cm³ = 0.01 dm³) of a 0.4 g/dm³ solution of sodium carbonate, m = 0.004 g.
Answer:
Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids or liquids even small insects. For the first time engineers have shown it is possible to stably trap objects larger than the wavelength of sound in an acoustic tractor beam. This discovery could enable the manipulation of drug capsules or micro-surgical implements within the body. The discovery could even lead to levitating humans.
