What chemical group does phosphate belong to?
The element P belongs to Group 15 (Vb), Nitrogen-Phosphorous- Arsenic group in the periodic table of elements.Phosphate is a weak, tri-basic anion PO43- but that's not a 'chemical group'.
Popquiz about current?
(Current-7)Current flows through a light bulb. Suppose a wire is connected across the bulb as shown. When this wire is connected...A: All the current continues to flow through the bulbB: Half the current flows through the bulb, half through the wireC: All the current flows through the wire.(Current-5)US Bulbs are rated for 120 V. European bulbs are designed for 240 V.If you buy a 100 W light bulb as a souvenir in Paris, and plug it in at home, what happens?A: It glows as usual, like a 100 W bulb should.B: Bzzzt, it burns out, too much powerC: It glows half as bright (powerful) as usualD: It glows 1/4 as bright as usualE: None of these/not enough info/don't know.(Current hmy-1)Electric companies generally tell their power customers the # of kilowatt-hours consumed in a month.What quantity is the power company telling you?A: power, duh!B: energy / timeC: timeD: energyE: None of these/impossible to determineF: current(Current_hmy-04)Rank in order, from largest to smallest, the powers dissipated in resistors a to d.R, DV+-R, 2DV+-2R, DV+-½ R, DV+-abcd1. a , b, c, d2. b, d, a, c3. b, c, a=d4. a=d, c, b5. b, d, b, c(Circuits-01)A battery with voltage ("emf") of 5V is attached to a resistor of resistance R.

VB program to convert meter to centimeter?
You can create a VB program to convert meters to centimeters by multiplying the meter value by 100. For example: Dim meter As Double = 2.5 Dim centimeter As Double = meter * 100 MessageBox.Show(meter & " meters is equal to " & centimeter & " centimeters.") This program declares a meter variable, converts it to centimeters by multiplying by 100, and displays the result using a message box.
Why Molecular bond Theory is better than Valence bond theory?
Molecular orbital theory is more recent than Valence bond theory. Both theories have their adherents and recently VB theory has had a renaissance. They both have their strengths. Chemists use both and mix/match. Some very familiar concepts used every day by chemists spring originally from VB theory, electronegativity, hybridisation of atomic orbitals. MO theory has its advocates, an early triumph was the prediction of the paramagnetism of O2 whereas valence bond theory predicted O2 to be diamagnetic. One criticism of VB theory is that it starts from a description of bonds as localised pairs of electrons, whereas in MO all bonds are potentially delocalised.
What is the resultant temperature when 2kg of water at 30degrees is mixed with 4kg of water at 90degrees?
there is no phase change and same liquid we can use this formula Tf =((Va*Ta)+(Vb*Tb))/(Va*Vb) Tf = Resultant temperature Va= Volume of tank A Ta= Temperature of tank A Vb= Volume of tank B Tb= Temperature of tank b

What element is in period 2 and group 7?
Nitrogen. There are actually two periods classified as "5", more properly "V" (Roman numeral 5). VB, towards the left side of the Table, and VA, towards the right. In Group 2, there is no Period VB, only Period VA, which is nitrogen.

you dont make vb vb is visual basics and you make stuff in it
Why vb is an event driven programming language?
because it is driven by events. as it is a language used in programming, then it only makes sense to say VB is an event driven programming language.
