While flipping a monster face-down in response to its activation, will generally not stop the effect's resolution, face-down monsters can't activate their effects at all.
(Sole exceptions; Big Shield and Mid Shield Gardna)
It is the act of being turned face-down that will send the Equip Spell Card to the graveyard, therefore one way to look at it is that Inzektor Centipede is already face down by the time the Equip hits the graveyard.
Because it is face-down at that time, it neither 'sees' the Equip hit the graveyard (so its trigger condition was never met) nor can it activate while face-down anyway.
Yes. Its only requirement is that it is sent to the graveyard. It doesn't have to be sent to the graveyard 'from the field' which is something that won't trigger if sent as XYZ material.
there are a fair few, but the ones that come to my mind first are shield warrior and necro gardna which can only activate in the graveyard. But not all effects involve removing from play such as volcanic shell.
No it does not activate, Neos Wiseman will be sent to the graveyard before it's effect can activate. So you won't receive any Life Points, nor will your opponement lose any.
It is a trap card so is spell speed 2, both for its initial activation and also its graveyard activation. It can be used in the battle phase, just not during the Damage Step.
Cards that go to the Graveyard are common knowledge, so the opponent has a right to see the one that you choose to send to the Graveyard. However, unless they have an effect in play that decrees otherwise, you do not have to show them the card that you choose to add to your hand.
The damage from Graverobber is applied when you activate the spell card.
No, sending three cards to the graveyard is a Cost to activate Charge of the Light Brigade. Because the cards specifically have to go to the graveyard, Macro Cosmos makes this cost unpayable, therefore CotLB cannot be activated.
After Molten Conduction Field resolves, Laval Volcano Handmaiden's trigger condition has been met. Since there's a valid target in the graveyard, she's allowed to activate and target it.
No. Infernity Necromancer has to be on the field to use its effect to special summons other Infernity monsters from the graveyard. Monsters can only special summon themselves from the graveyard if they specifically say they can activate in the graveyard - Plaguespreader Zombie for example. However even if Infernity Necromancer could activate in the graveyard, it is specifically prohibited from targeting a card called Infernity Necromancer anyway.
You would miss the timing to activate the card as the monster sent to the Graveyard must be last thing to happen. During a Tribute Summon, the monsters are sent to the Graveyard, but the last thing to happen is no monster being Tribute Summoned.
It will activate fine, the sent cards will just be removed from the game instead of going to the graveyard.

Odin says that if he is destroyed, you may resummon him by removing a Tuner from your graveyard, during that turn's End Phase, ie, the turn in which he was destroyed. If you have no Tuners that turn, then you can't activate this effect, and if you pass that turn's End Phase, then you have passed the time to activate it, so it does not matter to Odin if you get a Tuner in your graveyard after that.
No it does not activate, Neos Wiseman will be sent to the graveyard before it's effect can activate. So you won't receive any Life Points, nor will your opponement lose any.
As a matter of fact, yes. The end of Anubis does negate Stardust Dragon's effect as long as he is on the field. Since Stardust Dragon's effect activates in the graveyard, and The End of Anubis' effect states "Monster cards that designate a card(s) in the graveyard or activate in the graveyard are negated."
In general, a monster's effect can only be used while it is face-up on the field. If it can activate in a different zone, such as hand (Gorz, Emissary of Darkness) graveyard (Necro Gardna) or while banished (Stardust Dragon) then it will say so on the card. This is why a card such as Cyber Dragon cannot freely summon itself from the graveyard every time the condition is correct - it summons from hand. Evil HERO Infernal Gainer has no such text, therefore the cost of banishing it to activate its effect, can only be performed while it is face-up on the field.
